By the way, Andre, thanks yet again for the 417As. They are now about to
move from potato amp status to SET drivers. I think would like a little more power. I've just got a pair of FE127es to play with and have been in mad box-building mode. :-) -- Mick (Working in a M$-free zone!) Web:http://www.nascom.infohttp://mixpix.batcave.net My pleasure, Mick. Did I somehow miss the thread in which you told us the design of your potato amp? And, of even more interest, the speakers you used them with. And what the devil are FE127es? You're getting weirder and weirder Mick; soon you'll be insisting tube rectification sounds better than than those square black thingies lying dead with their legs in the air.

I had the full license to use potatoes winningly as I wanted. Why now, I was tree quarters Irish, because of me Irish mum, and because of me dad, two turds English. But other folks discovered other lesser known uses for potatoes as anti enemy agent. There is nothing so sweet as watching a horrible neighbour vainly trying to start his car after you've stuffed a couple of hard potatoes well up his exhaust pipe late the the previous evening. And now, yeah, what is an FE127? Are they not Foster five inch drivers? Patrick Turner. |

As to potatoes and exhausts - back in the day I was living in off- campus housing in West Philadelphia, there was a local pimp ("M.B. Terrell - Super Fly") as written on the door of his heavily modified Cadillac Pimpmobile) who used to drive down the block at all hours blowing many varieties of tunes on his air-driven horns. One day, Mr. Terrell parked his ride in front of our door - his house was round-the-corner, up the block... two big Idahos (the first foot of pipe was rectangular, so two spuds each needed) well up each pipe rammed with a broom-handle at about 4:00AM and a note on the windshield, two words "BE QUIET". The car was towed and the horns stopped. It was a gentler time back then. Today there would be random gunplay if that sort of thing was tried. But, Potatoes as ammunition for mischief have come a long way. http://www.spudtech.com/ Just for giggles: A "typical" Caddy pimpmobile: http://www.madle.org/ecorvorado.htm Did, by any chance, you cook the spuds on your motorcycle exhaust? That is another science in its own right. Peter Wieck Wyncote, PA |

Well... they are a bit like this: http://www.diyaudio.com/forums/showt...hreadid=109208 but I've resized them for the bigger drivers and added bracing. The top box is a reflex enclosure, the port being the full width slot across the back. This fires downwards onto a reflector (I don't think this is a "real" horn in that I don't think the horn section is either tuned or big enough to make a huge difference). The basic idea is that frequencies around Fs are reinforced, helping the bottom end a bit. I'll have a better idea in a couple of days when I've had a first listen. :-) Hopefully I'll be able to resist gluing them together long enough to get some photos! Unfortunately, the FE126e speakers, which I originally ordered, appear to be unavailable at the moment so I've used their shielded cousins. That has probably cost me some sensitivity. The 126s are supposed to be 94dBW and the 127s 91dBW at 1m, but the bass on the 126s is uneven and benefits from some series resistance. That loses some power and must surely make the damping worse, so perhaps I've not lost much. In answer to your earlier query, Andre, no, I didn't post anything about the spud amp. It was pretty basic and I just re-used my old OPTs - nothing special. It was actually built on the stripped chassis of my ECC82 paralleled PP amp so it looked extremely horrid too! The speakers aren't too bad, but are getting a bit old now. One of my brothers built them originally from a Wilmslow driver kit. I just wish he hadn't brush- painted them blue... :-( The new monoblock amps will be 417A and 6P3C (triode-strapped) to start with. I have plans to change the output bottle to 6C4C or 6B4G dht (much like 6.3v 2A3) later and to put a slightly more meatier OPT on them. That may have to wait until I've got Christmas over with though. So I start with about 1.4W and upgrade to nearly 3W! :-) -- Mick (Working in a M$-free zone!)

![]() I said.... I used to use boiled potatoes as my secret weapon in bike races over 100km. They did seem to work better than a Mars bar. someone replied..... Mars bars are rubbish. The lift doesn't last very long. What works is carbs. I carry a packet of fig rolls on my bike; highly recommended by the coach of the British mudbikers. When I was a rugby player, the team diet was fillet steak and all the potatoes you could eat. I went on a very hard bike ride 3 weeks ago, 108kms around a very hilly course, maybe 1,200metres vertical of climbing, with a lot at 8% gradient. I took 4.5 hours and although I started 1/2 an hour before the main field of maybe a 100 riders, I was third to finish at 15minutes behind 2 guys of about 30, so although I left 1/2 an hour early, I gave those guys a 30 year start because I'm 60. I wondered what kept them from passing me sooner than they did. I rarely ever eat when I am on a ride these days. As one ages, nearly everything one does gets more difficult to do except being wise perhaps. But trying to digest food while on the move on a bicycle is not something that improves with age. So I have never eaten during some of the 100km + training rides I do around town. 108km is a small ride by TDF standards, but it sure tested me. Potatoes seemed to be a reasonable fix but although they are natural complex carbohydrate, the calories per kg are low, and getting the calories to the muscles in a long ride is a being a little too optimistic. Simplistic ppl who think they can just eat while riding to make up for an absense of in-depth training are sorely dissapointed. The body and its workings is far more complex than most ppl think, and the glossy sporting magazine articles advertize all this stuff to eat but I doubt much works. I didn't quite do enough training for this long ride and found I was the living dead for the last 15kms, but then the wind was behind me and the day was overcast and it wasn't too hard a struggle. When 40 I could easily ride 150km in such terrain. But I must have done just enough training to get though. I passed others who'd begun earlier in the 160km route which was harder, and wondered how they'd ever finish. It was obvious to me they had no idea that it soon becomes MUCH more difficult to ride up a steep hill of say 8% gradient which is a couple of kilometres long than it is to ride a slight steep rise in their local suburb, maybe 100metres long. They didn't understand that after the first shocker of a really big hill, there are maybe another 5 more to follow, and each one takes its toll, and after several hours one's average speed can drop dramatically, and regardless of how easy one tries to ride up hill, and how low the gearing is on the bike. After 100km, I was going straight down to the lowest gear I wisely chose, 39 front cog x 27 rear cog. At 40 I rode 42 x 23. Age takes its toll. You are right about Mars Bars and Coca Cola. Same goes for all the rest of the absolute junk being sold around the shops. Its basically all complete rot gut, and all makers of this muck should have their manufacturing licences cancelled and the shops fined for selling non natural processed food. Don't get me strarted on food, but most of what is making so many arses so ****ing big and health problems so large is the food industry and substance industries. I mentioned my slight discomfort at the tail end of a decent ride to a young dude and he said eat carbo gel products, presumably tailored to be more slowly be absorbed without the body having to work so hard to do that in addition to prodiving an average of 200 watts of mechanical power. I have not tried his advice, but actually let myself get knocked up by such hard and difficult things so that the challenge better promotes fat loss and re-definition of muscle structure. 18mths ago I was 95kg, but now I seem to have settled at 75kg, and its extremely difficult to get weight any lower. A skin fold test would reveal I had a HIGH percentage of body fat of maybe 12%, as opposed to a lean elite athlete who is typically 8%, and if I was 8% now I'd be slightly faster up hills on the bike and might possibly rank amoung the top national cyclists in my age group, but I have NEVER been to of my heap ever. Compared to the top riders of my age group who need to have a large house with a couple of spare rooms for all the sporting trophies thay have won, I have very few trophies to show for a total now of about 110,000 kms I have ridden since 1986. But I don't regret one single kilometre. Between age 37 and 43 I rode 100,000km in training and weekly club races. The longer the race, the better I liked it. At club level, the elites didn't get all the fame. The handicapping system evened ppl out. But the best time trial for 25miles or 40kms I ever did was 1.06, and there were 3 guys in the club between 47 and 53 who'd clock very close to the hour. In a long race these guys didn't like the surging, and like me they couldn't sprint to save their lives, but against the clock on they own they were masters of pain and style. And they could maintain very unusually high heart rates for their age, and most were leaner than myself, to the point of looking emaciated. There was an abundance of the athletic gene in their make up. Not everyone has an abundance. Its not any use for anyone to try to force oneself to be the build that does not simply result from doing ample exercise and eating wisely. There are cyclists I have known who'd start each season heavy, and after a few rides would lean down to racing weight with ease, and beat everyone else. By comparision, I had to ride a lot further harder to get anywhere. 3 years ago, I had an operation on my knees and the doctors said I'd soon need a pair of titanium and plastic joints to stop the pain I was enduring. I couldn't even mow my own lawns... But the little cartlidge operation did improve things and I was able to get back into best personal form very close to where I was at age 40. Don't always believe doctors. They couldn't really say what had caused them to become so sore, I sure couldn't, but their fix seemed to work. Anyway, I thought riding a regular 200km a week would either wreck my knees, and i would need the joints, or it would improve my whole body, and stop the fast slide into fatness and rotting health that bedevils about 75% of the people I know of my age. I have had good improvement to health, and ride much faster than most ppl of 40, and I have NEVER been passed on the road by anyone my age during the last 18mths. Knee pain has reduced to almost nothing, and unlike 3 years ago when I couldn't stand up talking to someone for 10 minutes withouty looking for a chair, I am only slightly discomforted after a 100km ride, and there isn't any serious pains the next day. I also swim about 300metres daily which seems to be excellent for my back. Old verterbrea tend to slip out of place, and swimming is excellent for the back, and to balance the lack of motion of the arms while on the bike. Steak and potatoes isn't too bad, but some ppl have too much steak and too few potatoes, and if they do eat potatoes, its in the form of deep fried chips full of oil. The natural human diet is 10% protein, 10% fat, and 80% complex carbohydrate. I have always tried to keep to this idea, but aduring 14 years of doing very little exercize beyond lugging heavy tube amplifiers around, I was putting on about 1.4kg per year. It could have been 3 kg, but I know how to say no to absurd helpings of food and gallons of beer when its offered. As one toughens up to an exercize regime the body plays tricks because it becomes far more efficent and hence it becomes increasingly difficult to get to where the elite natural athlete is without having to try very hard. This morning I was on the road at 6.30am, and did a couple of long big hills in my course of 65km. I caught and passed a number of people, and stopped for a chat at the top of one hill. It was beautiful early morning at the top with mist hanging on mountain ranges and definately had an out of this world feel about it. It elates all the senses to get out and do something. Meanwhile, I think the worst horn sound I heard did use Foster 5" speakers in tractrix horns home made buy a guy who tried hard. No success though. The sounded like the sound was trapped inside a close wooden box. There are many examples of horn speakers which are simply expensive firewood. Patrick Turner. Inevitably, I collected the name, Potato Pat, and I didn't mind. I had the full license to use potatoes winningly as I wanted. Why now, I was tree quarters Irish, because of me Irish mum, and because of me dad, two turds English. Well now, Padraig... And now, yeah, what is an FE127? Are they not Foster five inch drivers? Yeah, I shoulda seen the clue in Mick's "mad box building" but I took that to mean he was drilling a chassis for these weird FE127es tubes... Fostex, eh? I heard about them: Japanese-style Lowther type point source speaks with whizzer cones. Said to be very nice indeed in tapered quarter wave pipes. Indeed, I once published a design that could be used interchangeably with 8in Lowthers and the equivalent Fostex drivers, with someone reporting on the single driver conference that the Fostex went a bit deeper in my design than the Lowther. Personally, I hated the design, because with the Lowther it was very sensitive to just how you stuffed the area behind the driver, otherwise you got a screechy treble overwhelming everything, which had to be fixed with stupid little tufts of wool between the whizzer and the main cone; I hate that sort of kludging, and don't care overly much for those who try to promote it as "tweaking". In my Fidelio type horns the Lowthers work without that sort of messing around; of course, my smallest Lowther horn has four times the footprint of a TQWP, so there is a certain wife acceptance factor involved for the young at heart. What sorta boxes did you build for the Fostex, Mick? Well... they are a bit like this: http://www.diyaudio.com/forums/showt...hreadid=109208 but I've resized them for the bigger drivers and added bracing. The top box is a reflex enclosure, the port being the full width slot across the back. This fires downwards onto a reflector (I don't think this is a "real" horn in that I don't think the horn section is either tuned or big enough to make a huge difference). The basic idea is that frequencies around Fs are reinforced, helping the bottom end a bit. I'll have a better idea in a couple of days when I've had a first listen. :-) Hopefully I'll be able to resist gluing them together long enough to get some photos! Unfortunately, the FE126e speakers, which I originally ordered, appear to be unavailable at the moment so I've used their shielded cousins. That has probably cost me some sensitivity. The 126s are supposed to be 94dBW and the 127s 91dBW at 1m, but the bass on the 126s is uneven and benefits from some series resistance. That loses some power and must surely make the damping worse, so perhaps I've not lost much. In answer to your earlier query, Andre, no, I didn't post anything about the spud amp. It was pretty basic and I just re-used my old OPTs - nothing special. It was actually built on the stripped chassis of my ECC82 paralleled PP amp so it looked extremely horrid too! The speakers aren't too bad, but are getting a bit old now. One of my brothers built them originally from a Wilmslow driver kit. I just wish he hadn't brush- painted them blue... :-( The new monoblock amps will be 417A and 6P3C (triode-strapped) to start with. I have plans to change the output bottle to 6C4C or 6B4G dht (much like 6.3v 2A3) later and to put a slightly more meatier OPT on them. That may have to wait until I've got Christmas over with though. So I start with about 1.4W and upgrade to nearly 3W! :-) -- Mick (Working in a M$-free zone!)

The lift doesn't last very long. What works is carbs. I carry a packet of fig rolls on my bike; highly recommended by the coach of the British mudbikers. When I was a rugby player, the team diet was fillet steak and all the potatoes you could eat. I went on a very hard bike ride 3 weeks ago, 108kms around a very hilly course, maybe 1,200metres vertical of climbing, with a lot at 8% gradient. So now we know where you've been since then: under medical care. I surely would be if I tried 108km! A good ride for me is 22km. Try black or dark blue clothes. They make you look slimmer. Today I lunched at Isaac's in McCurtain St in Cork, on tapas, roast pheasant with a jus of red wine, spicy pear tart with butterscotch sauce, washing it down with a bottle of Guignal Cotes de Rhone and that distillation of sunshine, the Barton reserve Sauternes for a desert wine. I was planning on cycling when I got home but it is absolutely ****ing down. I doubt I shall ever weigh 75kg but then I never did. Even when I earned my living as a professional sportsman, I never broke 190lbs to the downside, which was acceptable for someone my height and bigboned, so perhaps it is a triumph for the sedentary intellectual in several decades to have put on only another stone. (That collage of measuring standards should confuse the French!) Andre Jute I took 4.5 hours and although I started 1/2 an hour before the main field of maybe a 100 riders, I was third to finish at 15minutes behind 2 guys of about 30, so although I left 1/2 an hour early, I gave those guys a 30 year start because I'm 60. I wondered what kept them from passing me sooner than they did. I rarely ever eat when I am on a ride these days. As one ages, nearly everything one does gets more difficult to do except being wise perhaps. But trying to digest food while on the move on a bicycle is not something that improves with age. So I have never eaten during some of the 100km + training rides I do around town. 108km is a small ride by TDF standards, but it sure tested me. Potatoes seemed to be a reasonable fix but although they are natural complex carbohydrate, the calories per kg are low, and getting the calories to the muscles in a long ride is a being a little too optimistic. Simplistic ppl who think they can just eat while riding to make up for an absense of in-depth training are sorely dissapointed. The body and its workings is far more complex than most ppl think, and the glossy sporting magazine articles advertize all this stuff to eat but I doubt much works. I didn't quite do enough training for this long ride and found I was the living dead for the last 15kms, but then the wind was behind me and the day was overcast and it wasn't too hard a struggle. When 40 I could easily ride 150km in such terrain. But I must have done just enough training to get though. I passed others who'd begun earlier in the 160km route which was harder, and wondered how they'd ever finish. It was obvious to me they had no idea that it soon becomes MUCH more difficult to ride up a steep hill of say 8% gradient which is a couple of kilometres long than it is to ride a slight steep rise in their local suburb, maybe 100metres long. They didn't understand that after the first shocker of a really big hill, there are maybe another 5 more to follow, and each one takes its toll, and after several hours one's average speed can drop dramatically, and regardless of how easy one tries to ride up hill, and how low the gearing is on the bike. After 100km, I was going straight down to the lowest gear I wisely chose, 39 front cog x 27 rear cog. At 40 I rode 42 x 23. Age takes its toll. You are right about Mars Bars and Coca Cola. Same goes for all the rest of the absolute junk being sold around the shops. Its basically all complete rot gut, and all makers of this muck should have their manufacturing licences cancelled and the shops fined for selling non natural processed food. Don't get me strarted on food, but most of what is making so many arses so ****ing big and health problems so large is the food industry and substance industries. I mentioned my slight discomfort at the tail end of a decent ride to a young dude and he said eat carbo gel products, presumably tailored to be more slowly be absorbed without the body having to work so hard to do that in addition to prodiving an average of 200 watts of mechanical power. I have not tried his advice, but actually let myself get knocked up by such hard and difficult things so that the challenge better promotes fat loss and re-definition of muscle structure. 18mths ago I was 95kg, but now I seem to have settled at 75kg, and its extremely difficult to get weight any lower. A skin fold test would reveal I had a HIGH percentage of body fat of maybe 12%, as opposed to a lean elite athlete who is typically 8%, and if I was 8% now I'd be slightly faster up hills on the bike and might possibly rank amoung the top national cyclists in my age group, but I have NEVER been to of my heap ever.

So now we know where you've been since then: under medical care. I surely would be if I tried 108km! A good ride for me is 22km. The event I went in arranged by Pedal Power was the 'Thawa Challenge'. http://www.pedalpower.org.au/events/...0challenge.pdf Other events for the day were the 'Epic', at 210km, with around 3,300metres of hills, and 'Classic' at 160km, maybe 2,000m of hills. For beginners and weaklings, there was the 'Tidbinbilla' of 50km. One guy of 29 did the Epic 210km in 7.5 hours. It was his 9th try. And he isn't anyone who we might see soon in the TDF like Cadel Evans. There were about 450 entrants for the 4 groups of riders on the day, down on last year probably because of the increase on the entry fee because of the increase on insurance premium because a guy got killed last year riding down Fitz's Hill. The whole event is named after Fitz. We don't know who he was, maybe a german immigrant who loved roaming up these hills, but we all sure know this hill. It is a 10% gradient over a full 2.8km distance, so riding up it sorely tests everyone. The first 1/2 km seems fine, you know are being challenged. The second 1/2 km you realize you need to go for a lower gear and you can forget all about what you read in the books about climbing hills. During the next km your world view darkens, torture begins and you begin to realize your'e being punished for existing, and the world is being seriously unfavourable. The last km teaches you dissapointment. Just when you are thinking its near the end of the climb, a view ahead around yet another bend confirms you must die for slightly more distance.... But at the top of this hill one feels great relief, because nothing worse is to follow. If one has been wise, one will have benefitted from fitting an extra low gear. Last time I did this hill in about 1990, I used 42 x 23 and struggled. Then once over this brute of a climb, there are steep descents and more climbs until the end of the sealed road appears, and you turn around to return. If one wanted to keep going and make a loop for the day there would be another 150km extra, and much gravel road, and full of severe mountainous climbs and descents. Returning down Fitzs hill is somewhat tense experience. If one is riding on one's own one may just freewheel down and reach rather exciting speeds for a bicycle, and not have to worry about slower other riders ahead, or faster ones passing. Sometimes a kangaroo can hop out of the bush suddenly. This is always a very nerve wracking experience. Its happened a few times to me but fortunately not on this hill and not when quickly descending others. I have ridden this hill a few times years ago and maybe I hit 80km/hr. But guys who have seriously raced down this hill have clocked up to 120kph, pedling furiously to maximize speed. So when inevitably someone managed to hit something or fall off at between 80 and 100kph, it was always going to be a serious accident, and one a long way from any medical assistance, and it'd be so easy to bleed to death in the middle of knowhere. Thousands of kangaroos end their lives each year this way after being hit by cars and lorries. Try black or dark blue clothes. They make you look slimmer. No, I'd get mistaken for a priest, policeman, or crazy artistic type, audio tech, and good for nothing poseur. Today I lunched at Isaac's in McCurtain St in Cork, on tapas, roast pheasant with a jus of red wine, spicy pear tart with butterscotch sauce, washing it down with a bottle of Guignal Cotes de Rhone and that distillation of sunshine, the Barton reserve Sauternes for a desert wine. There are not many really decent restaurant or cafes here worth cycling 50km across town where you can park a bike beside the table outside. Its far cheaper to dine at home after a ride. Nevertheless, I often stop at one cafe in town on the way home after a ride and get a hot chocolate and a choclate fudge biscuit for USD $6.00. I was planning on cycling when I got home but it is absolutely ****ing down. The eternal cyclist's worry is whether it will rain or not. But here the average rainfall for the last 10 years has reduced to about 40% of "averages" before 2003. http://www.enviro-friendly.com/average-rainfall.shtml Water is becoming a scarce thing, and the supply dams for the Canberra might actually run dry. Climate change is having a very drastic effect on Australian water supplies. Cycling has become very popular compared to 20 years ago when almost no women took part, and ppl and staff looked at you strangely in cafes when you appeared in lycra knicks. Now the waitresses look at me as if they fancy me. Us cyclists are the healthiest customers. And the waitresses are dishes on legs, and I'd quite like to be 30 again to fix 'em up. But I only end up soaked through after riding 50km in ****ing rains maybe once a year now if I get caught in an afternoon storm. It used to happen much more often. I rode in 5 consecutive Canberra Tours held in autumn, and in 3 it ****ed rain for a lot of the races. People entered in my grade wouldn't enter in day 2 either because of the weather, or because they hadn't got into the the first 10 places on day 1, and wouldn't earn any prizemoney to pay for the motel. Cyclist's are eternally tight arsed with money. So this allowed me to get a much higher placing as a local. I recall doing the third and and last ride on a sunday of about 70km, and it rained and sleeted for the whole race, but only about 20 entrants out of the full 60 turned up to start. I went into such 'open' events because it attracted the fittest ppl from around NSW, and gave me real competition, and quality training. I never did well because most were years younger, some 20 years younger, and it was a scratch race event, all off together, and old farts like me had no chance for a win. But I sure didn't come last. I was aways better for weeks after in the local club races during the following winter. As a much older farter at 60 I have no desire to enter any 'open' races with all ages now. There come a time when it becomes easier to reach one's limits of endurance at an older age because usually a dodgy back or knee or something else tells you there is a definite limit. Training hard gets you to a level of fitness which becomes very difficult to improve, and one knows that its all downwards as years pass, and a day will come when wheels are hung up for good. But between now and then I hope to merely enjoy the bicycle. I don't have the time or inclination to race again in the local Veterans Club. Its mainly full of young fellas of 40. They hold races way across town, way up the back of lonely roads and because of the insurance premiums, its not cheap to race while on a low income as an audio tech. I doubt I shall ever weigh 75kg but then I never did. Even when I earned my living as a professional sportsman, I never broke 190lbs to the downside, which was acceptable for someone my height and bigboned, so perhaps it is a triumph for the sedentary intellectual in several decades to have put on only another stone. (That collage of measuring standards should confuse the French!) Hmm, most ppl who say they are "big boned" are simply chubby. The simple test is to wrap thumb and second finger around an opposite wrist. If you cannot touch finger to thumb, you have a thick wrist and you are either big boned or fat, or both. I couldn't get the gap below 12mm two years ago, but if I squeeze hard enough, I just can do it now. But I have seen guys who have 12mm overlap, and it indicates a low bone diameter to length ratio. Invariably, such guys are always faster on a bicycle than I am because they have at least my horsepower, but are 10kg lighter, and when moving less body volume through air there is less drag, and when going uphill, they are taking it easy while I am flogging myself to death keeping up. But when these light framed guys fall off, they very commonly come down rapidly on a shoulder and a collar bone snaps like a matchstick. I have fallen twice very hard onto my shoulders, and broken nothing, sore for 3 days, back riding on day 4, racing again on day 10. I should definately have been a rower, or perhaps a long distance swimmer, not a cyclist, but on the water there are no down hills, and in the pool there is only the view of the pool bottom, a black line, and its so boring compared to the travel on wheels. The fastest heavy tall man in pre 1996 Tours De France was Miguel Indurain. http://en.wikipedia.org/wiki/Miguel_Indurain I have the same height and weight as Miguel. But Miguel has a much much bigger internal engine than I was ever born with. I am quite feeble by comparison.... But Miguel does not understand triodes... Patrick Turner.

I have not tried his advice, but actually let myself get knocked up by such hard and difficult things so that the challenge better promotes fat loss and re-definition of muscle structure. 18mths ago I was 95kg, but now I seem to have settled at 75kg, and its extremely difficult to get weight any lower. A skin fold test would reveal I had a HIGH percentage of body fat of maybe 12%, as opposed to a lean elite athlete who is typically 8%, and if I was 8% now I'd be slightly faster up hills on the bike and might possibly rank amoung the top national cyclists in my age group, but I have NEVER been to of my heap ever. Compared to the top riders of my age group who need to have a large house with a couple of spare rooms for all the sporting trophies thay have won, I have very few trophies to show for a total now of about 110,000 kms I have ridden since 1986. But I don't regret one single kilometre. Between age 37 and 43 I rode 100,000km in training and weekly club races. The longer the race, the better I liked it. At club level, the elites didn't get all the fame. The handicapping system evened ppl out. But the best time trial for 25miles or 40kms I ever did was 1.06, and there were 3 guys in the club between 47 and 53 who'd clock very close to the hour. In a long race these guys didn't like the surging, and like me they couldn't sprint to save their lives, but against the clock on they own they were masters of pain and style. And they could maintain very unusually high heart rates for their age, and most were leaner than myself, to the point of looking emaciated. There was an abundance of the athletic gene in their make up. Not everyone has an abundance. Its not any use for anyone to try to force oneself to be the build that does not simply result from doing ample exercise and eating wisely. There are cyclists I have known who'd start each season heavy, and after a few rides would lean down to racing weight with ease, and beat everyone else. By comparision, I had to ride a lot further harder to get anywhere. 3 years ago, I had an operation on my knees and the doctors said I'd soon need a pair of titanium and plastic joints to stop the pain I was enduring. I couldn't even mow my own lawns... But the little cartlidge operation did improve things and I was able to get back into best personal form very close to where I was at age 40. Don't always believe doctors. They couldn't really say what had caused them to become so sore, I sure couldn't, but their fix seemed to work. Anyway, I thought riding a regular 200km a week would either wreck my knees, and i would need the joints, or it would improve my whole body, and stop the fast slide into fatness and rotting health that bedevils about 75% of the people I know of my age. I have had good improvement to health, and ride much faster than most ppl of 40, and I have NEVER been passed on the road by anyone my age during the last 18mths. Knee pain has reduced to almost nothing, and unlike 3 years ago when I couldn't stand up talking to someone for 10 minutes withouty looking for a chair, I am only slightly discomforted after a 100km ride, and there isn't any serious pains the next day. I also swim about 300metres daily which seems to be excellent for my back. Old verterbrea tend to slip out of place, and swimming is excellent for the back, and to balance the lack of motion of the arms while on the bike. Steak and potatoes isn't too bad, but some ppl have too much steak and too few potatoes, and if they do eat potatoes, its in the form of deep fried chips full of oil. The natural human diet is 10% protein, 10% fat, and 80% complex carbohydrate. I have always tried to keep to this idea, but aduring 14 years of doing very little exercize beyond lugging heavy tube amplifiers around, I was putting on about 1.4kg per year. It could have been 3 kg, but I know how to say no to absurd helpings of food and gallons of beer when its offered. As one toughens up to an exercize regime the body plays tricks because it becomes far more efficent and hence it becomes increasingly difficult to get to where the elite natural athlete is without having to try very hard. This morning I was on the road at 6.30am, and did a couple of long big hills in my course of 65km. I caught and passed a number of people, and stopped for a chat at the top of one hill. It was beautiful early morning at the top with mist hanging on mountain ranges and definately had an out of this world feel about it. It elates all the senses to get out and do something. Meanwhile, I think the worst horn sound I heard did use Foster 5" speakers in tractrix horns home made buy a guy who tried hard. No success though. The sounded like the sound was trapped inside a close wooden box. There are many examples of horn speakers which are simply expensive firewood. Patrick Turner. Inevitably, I collected the name, Potato Pat, and I didn't mind. I had the full license to use potatoes winningly as I wanted. Why now, I was tree quarters Irish, because of me Irish mum, and because of me dad, two turds English. Well now, Padraig... And now, yeah, what is an FE127? Are they not Foster five inch drivers? Yeah, I shoulda seen the clue in Mick's "mad box building" but I took that to mean he was drilling a chassis for these weird FE127es tubes... Fostex, eh? I heard about them: Japanese-style Lowther type point source speaks with whizzer cones. Said to be very nice indeed in tapered quarter wave pipes. Indeed, I once published a design that could be used interchangeably with 8in Lowthers and the equivalent Fostex drivers, with someone reporting on the single driver conference that the Fostex went a bit deeper in my design than the Lowther. Personally, I hated the design, because with the Lowther it was very sensitive to just how you stuffed the area behind the driver, otherwise you got a screechy treble overwhelming everything, which had to be fixed with stupid little tufts of wool between the whizzer and the main cone; I hate that sort of kludging, and don't care overly much for those who try to promote it as "tweaking". In my Fidelio type horns the Lowthers work without that ... read more |

I note that you'll go to extreme lengths to stay on topic though! :-) 99% of readers at rec.audio.tubes are probably not into riding a bicycle. 90% proably regard bicyle travel of any kind to be third world transport and extremely prone to bad accidents happening, and if what I have heard about most US cities is true, i wouldn't want to ride a bicycle anywhere in the US. However, one Lance Armstrong did challenge other Texan road uses with his presence and live to win the TDF a record 7 times in a row. What he had to say to drivers of cars, lorries and buses isn't flattering after they all took turns to casually run him off the road umpteen times while he was out training. Just think, surviving the traffic in Texas on a bicycle takes some doing. But maybe Sydney traffic is worse. Lance also survived a very life threatening bout of testicular cancer before winning those 7 in a row. Lance doesn't know much about triodes either. But a bicycle can make a weak flabby gutted man into a tiger of fitness, which most ppl of 60 try to avoid being. They might die. Well of course ya might ****in die. Any time. But a guy I raced when he was in his 70s about 20 years ago just died at age 91. Hubert Opperman died after riding bikes all his life at 90. For the 1% who dream of an alternative existance, a bicycle is a way to get there. I also hate gymnasiums, with the smell of sweat, grubby gear, loud music, enclosed space, anti social and unconvivial atmosphere, being fenced in, jerks selling steroids, and so on, etc, so give wide open spaces, a vacant road ahead... On cool days a following breeze is welcome, and on hot days a headwind keeps you cooler than a tail wind. I don't take boiled potatoes on rides with me now. They actually are hard to digest when on the move. I just take clean water, or sometimes green tea. I find the severe exercize suppresses hunger until I have done over 100km, when I begin to dream of roast beef surrounded by baked potatoes. But I never eat such a meal. It appears my body has wised up to the tricks my mind plays upon it, and despite the permanence of my frugal diet eating loads of greens and adequate small quanties of bread and complex carbohydrates and lean meats, it refuses to get leaner. Had I tried to lose weight by diet alone it would have been a complete failure. One needs to create a calorie account deficit. 8 hours of cycling with heart rate 50% above resting give an average weight person a calorie use of about 400 per hour above what it is while working in an office or relaxing at home being sedantary. 8 hours equals 3,200 calories. But because one rides say 3 days a week to manage 8 hours a week total, the metabolism is speeded up outside excercize times and you burn a lot more. There are 9,000 calories in a kilogram of fat, oil, butter etc. So without much trouble I managed to burn off 9,000 calories worth of fat each week of cycling. Sugars, dry weight of carborhydrates and protein have about 4,500 calories per kilogram. So a few spoonfuls of sugar in coffee is OK, but forget thak ****in Coca Cola and other fizzy drinks. Modern western nation McDonald's type food is 80% fats and nutrient free sugar with chemicals. only 20% is good for you with the small amount of necessary proteins for more than adequate survival. So if you eat wrong, change this to eating 10% of fats and nutrient sugars, and 10% of proteins, and 80% of complex unrefined carbohydrates. Learn what IS in food, and realize what the *******s of industry have removed, and what they are slowly poisoning you with; eg, hyrogenated fats for making food stay "fresh" for months on store sheleves. These are bad for the heart. Its years since I bought butter or margerine, and i just use olive oil on the salads I make from whatever fresh green vegtables are low priced on the day in the store. Good eating does not need to be expensive, and although I enjoy a meal at my regular cafe weekly, I laugh at the small amount of grenery appearing on my plate. For me there was only one way to lose weight, pedal the fat off. It came of at a kilogram a week for several months, then the loss leveled abruptly, despite the continuation of eating plenty of stuff with very few calories, but with plenty of vitamins and minerals. Most ppl's bodies crave these things, but they are missing from most processed foods on supermarket shelves. Processesd food is laced with corn syrup and chemicals to make you want more and buy more. And you make a vain attempt to gain balanced nutrition by eating this junk food to get the nutrition values which food companies find un-profitable to sell. Because people with lotsa domani are sitting ducks for the disease of affluenza, they get large waists and eat more because they get a kind of mental compulsion which is an anxiety symptom built into affluenza. Well off people do not eat because they are hungry. So I figured my body easily switched to fat fuel for awhile, and when the fat tank got low, my body decided to change again and become much more efficient, and even looking at a cake forsale at a cafe makes my body gain weight. To explain its refusal to continue losing weight, I think it probably now derives energy from plant materials which were previously just passed along because easier targets were available, and low energy demands were being made, and testosterone was low with it. For millions of years our bodies evolved to look for food because we got hungry, and we all got hungry because we'd worked to find food. Never having quite enough is good for you. Heart disease rates plummeted in the UK during WW2 when food was rationed. The Poms still beat Germany though. Both sides did know about triodes though. And in fact, without many boxfulls of triodes, it was difficult to reduce the average life expectancy resulting from war, not a happy consideration. One does need a box of triodes in a tank or a V2 rocket. The wartime healthier leaner population tended to live longer and have less serious road accidents because they mostly rode a bicycle to work, and ate sparingly. Pictures from the period show women never looking so fresh, beautiful and natural and slim. After WW2, these very ppl all junked the bike, bought a car, and killed each other on the roads instead of shooting enemies and being shot. Then they ate too much, drank far too much, got fat, and died early. Just whether they were happier is a moot point. The up and coming generation of youngsters is PC screen fixated, and dominated by communication operated by thumb presses. They are bombarded by BS for much of their time on Earth, and they give in to BS so easily. Affluenza is creating an Earth not worth livin on. Too much hot air and combustion product. They are tending to become fat arse zombies incapable and unwilling to do anything very much compared to previous generations - except getting things they think they want as cheaply and easily as possible. There is a silver lining though. As ppl become more affluent, money oriented, and educated, they tend to become far more selfish and dysfunctional in relationships. The rising divorce rate proves it. So then they have less children. The younger generation can see how difficult it is to go through a life and that making new children are a big sacrifice, and for the young, "sacrifice" is a complete no-no. So when your son of 32 laments his wife just left him for yet another set of boring frivolus reasons, rejoice, for it is an excellent result for the Planet. What the world needs is one child per couple absolute maximum until we get the problems fixed first to permit more than 1, but I doubt that will ever happen because youthful love propels pregnancy rates and is all about irrationality, and doing things without thinking of the real issues and consequences while having an extended wish list for affluent living.
