Where did all the tubies go?
Andy Evans is right. There used to be real tube talk on RAT. Now
there's a bunch of tacky radio restorers and fools with a dire self- image shortfall. Yech! I go away for a couple of weeks to do bike electronics and return to find hardly anything worth reading and only one intelligent question -- from West -- worth answering. The same people are still beating internal NFB in triodes to death with pinpricks. Sheesh, fellers, either you believe the observable anomalies in triode results is caused by invisible NFB, or you conclude that pentodes are naturally, permanently and irredeemably (nice word on Easter Sunday) inferior. But neither party will convince the other. What a waste of time.

But some of us actually do some exercize, and while on a bicycle at the same time. 15 years ago I had a cyclometer which worked off magnetic pulses off the rotation a little magnet on the front wheel. I was able to record time of the ride elapsed, and average speed, and full stop watch function, so i could measure the distance I'd raced or trained, and how long I'd taken, and by how many minutes I had been beaten when I saw the winner's time in the newspaper on the monday after saturday's race. The damned thing didn't tell me about the weather though, and it got soaked internally a a few times, and had to be replaced. I stopped cycling for about 13 years and took it up again last July, but at 59 I don't need to know anything exactly about what I do on the bicycle. Its a bit like I don't need to analyse everything that can be analysed with amplifiers I build now. I'm not competing seriously anymore, but if I did I'd probably go about the same speed as other guys of 59. Big deal. Its a lot slower than the guys of 29 go. I just can't get a big kick out of trying to be leader of the pack any more, or even just being part of the pack, which was mainly why i raced; the cut and thrust of competion is intoxicating while you are young, but somewhat knee busting now, and I'm less social. And nowdays, if I had any kind of electronic meter on the bike, it'd be all what the old meter was and have a heartrate monitor. And and something to tell me how many calories I'd burned, and such a thing would have all the other bells and whistles now possible that were not available 15 years ago like having a complete history of the ride stored in memory, hil climb elevation changes, speed changes, and all downloadable into a PC for display and analysis along with heart rate counts, fat burn counts, carbobhydrate burn, maybe even water use. Maybe even GPS positioning, map related, so the streets I'd ridden down could be identified... I say "If" I had a meter now. I don't yearn for one; I know when a hard hill climb has nearly caused a heart attack while I overtook a 39 old. I don't need to have a meter tell me I have revved the heart more than my doctor would approve of. I shouldn't really fear though because I have always found it impossible to raise my heart rate enough to theoretically move enough blood around fast enough to be able to get a good time trial time. Other guys find this much more easy, so they get better times, so perhaps their own body's internal electrical signals involving will to go for it, and heart stimulation signals and pain bariers are all more functional than mine. Do they more likely die of heart failure? Who knows, one takes a chance or two or one lives a dull life. Seems like all this stuff can now be measured more fully.... If I was 25 and considering trying to win the Tour De France, training with something that allowed full and complete measuring of me and my effort for the best coaches to view could well mean the having a real racing edge, and earn me lots of money, so electronics on bikes isn't as silly for some as you may think. I imagine Lance Armstrong, one of the best cyclists that this recent era has produced probably was well monitored electronically and guided by what was measured. The chess world is now dominated by electronics, ie, computer analysis. If you want to be world champion, you must study all the past recorded games of your future oponents, and apply Deep Fritz 8 etc, and be able to remember what moves to to play on the day of a tournament. Everyone playing chess seriously is furiously reading books AND using chess playing programs which play better than 99.9999% of all human players. The quality and complexity of reasoning used in the top games now played has never been greater. I can't bring myself to waste time playing serious club based chess, and it'd be painful. I'd lose against the loliest of the club players. But hey, none of those guys ride very far on a bicycle, and not a single one one them takes music seriously, or knows about triodes, or has ever built anything electronic. Many are dangerous trying to do any trade work. But a few are math teachers, and the very best are usually only good at chess, all other things seem to be a bit dodgy, like relationships, holding jobs down or staying sane and not obsessive. Electronics is heare to stay and affects all our lives, and will intrude more and more. Cures for Alzimers disease could include consciousness chips being implanted to replace old fuddy duddy ****ed up organic brain cells...... The future with electronics beckons as we heard very gradually and slowly toward real and applyable artificial intelligence. And no doubt chess playing implant chips might revolutionize chess as we know it, and the brightest players in 100 years may have a damned head full of silicon. Drinking a few cups of coffee won't brighten up your game. Blokes should be able to ride bicycles a lot faster in 2107, weather permitting, since many people then will have genetically engineered physiologies, since we will have cast off the present inhibitions to such progress. There is a lot of money to be made in all this electro-trickery smoke and mirrors. Patrick Turner. |

Where did all the tubies go?
On Apr 8, 9:48 am, "Andrew Jute McCoy" micturated:
I go away for a couple of weeks to do bike electronics and return to find hardly anything worth reading and only one intelligent question -- from West -- worth answering. "Bike electronics" for the calculator-challenged... much as your KISS amp is for the electronically challenged. The former tells you nothing that a simple calculator, your weight and average speed can't tell you... and the latter does nothing at tall. As to your Timmee... you do have it well-trained, I admit. At least you have accomplished something with an observable result. Oh, let's see *your* answer to that question.... Should be fascinating. Peter Wieck Wyncote, PA |

Sure, I have one of those too, a Ciclosport HAC4, which along with my heart rate, the altitude, the pedalling cadence and many, many more functions than I ever had time to read about (multiple stopwatches for heart recovery rates in various aerobic bands), actually tells bike speed and distance. But its main advantage is that I easily gimmicked the Windoze software that came with it to work on my Mac, so I can send printout of my exercise to my doctor. Never do, of course, now that the echo-scans discovered I have the heart of an ox. But that's not the sort of electronics I'm talking. This is heavy stuff, adaptive suspension and electronic gearchanges in various modes. See my other post in which I put Poopie down; there's a more detailed description in there.

At the very least, you'd think they could give the granny next door a croggy to the supermarket. Ian Really, Iveson, the educational authority which entrusts the minds of the next generation to you must be smoking bad dope. You're as bad as that moron Worthless Wiecky, and that public nuisance Poopie, automatically assuming I'm talking about some little bike speed computer. What makes it worse is that you have had years of opportunity to notice (and we know from comments by you that did notice) that with me it is never simple, yet you still make the same bovine footinthemouth error, you still dive facefirst into the same pit I stake for genetic detritus like Worthless and Poopie. And not just once, twice. You also assume, without the slightest evidence, that I cycle because I am Green. There are a million other reasons for cycling. Being poor. A desire to be fit. The pleasure of the quiet lanes in the countryside. Breathing fresh air. For your information, no, I wasn't talking about some little bike speed computer, I was talking about electronically adapted suspension and electronically changed gears, and other electronic services on the bicycle. And no, while my reasons for cycling are none of your business, I'm no kind of Green; if you had been paying attention in this very conference, you would have learned repeatedly that I despise the Greens as exceedingly dangerous fanatics and wreckers, indeed as mass- murderers (for instance by banning harmless DDT, which in turn frees the mosquito to kill millions of the most defenseless people in the world, including children), a form of received religion entirely immune to scientific enquiry. You're wrong on two counts out of two, Iveson. Par for the course. I really thought you had more brains than Worthless Wiecky. I'm disappointed in you. Once in while, before it is too late, you should try putting your mind in gear. Who knows, you might like the experience enough to make a habit of it.

I laughed out loud when I read that. Order is for the fascist mentalities like Worthless and Yeager and control freaks like Poopie. Their impulse isn't actually order, it is control, so that no one can rise above them and make them feel inferior; for that inferior, obscene motive, they intend to stunt everyone to their depressing level of stupidity and lack of achievement. Intelligent people with something to contribute thrive on disorganized chaos. No, I'm under no illusion that my "order" will be any better than that instituted in the most despicable dreams of Ludwig and Iveson, the resident Ur- Communists, just more amusing.

In addition or, rather, in subtraction, I am also designing a stainless steel frame that will be lighter than the thick ali of my original hub gear Gazelle Toulouse by many kilo, and lighter even by a kilo or so than the Trek ali chassis I currently have the electronic gear on. All in all, the electronic bike will be about 6 or 7 kilo, possibly as much as 15 pounds, lighter than the old one... Okay, so some people have entire racing bikes that weigh that much; so what -- I'm not racing, I'm taking in the scenery or talking, taking social rides. The less I have on the bike, the better. So I clean it sometimes. Clean it? You're joking, of course. I used to drive really filthy Porsche (in sunshine yellow, so the filth would really stand out), and once threatened to fire a driver who insisted on washing and polishing the Bentley. My experience is that people think that anyone who can drive a car that filthy will also not care if it is crushed a little against their shining, polished pride and joy, and consequently are in a real rush to get the hell out of my way. I don't wash my bike either. On the Gazelle I sit taller than the drivers of Range Rovers, bend to look them in the eye, then cut them off in traffic with impunity. If my bike were clean, they'd cut me off; most of those buggers, and all their wives, have no idea at all about where the corners of their landyacht are. They'd hit me for sure if they saw a clean bike and thought I cared, and consequently cut me off. I dunno any shiela across town who's worth rooting after hours, so I don't need lights.

I ride up the hills without thinking about which gear to be in, without wasting time and energy being in the wrong gear, and trying to remember whether the 31 gear inch ratio is two up at the front and four down at the back or some other forgotten combo. All I do is punch the button under my right thumb twice to drop the gearbox mode from sport through normal into little old lady mode, which is good for hills. The sports mode won't let me use a gear lower than second, and the normal mode is what I already have on another bike, which is just the eight hub gears at my normal energy expenditure -- I dinna spend the money to do the same thing! But the little old lady mode (Shimano calls it L for leisure) lowers the expected rate of work so that on a familiar hill my pulse rate was 30bpm lower than when I went up there the previous week on a manual bike. The ascent was clearly easier. That the electronics automatically harden or lock out the suspension when you're travelling slowly or steeply uphill also helps, and probably substantially, but I can't see how one would reliably quantify the contribution of the adaptive suspension. and they don't slow headwinds, which should all be blowing slower because countless windmills have been erected all over the country to stop greenhouse emissions, and ruin the tranquil views that attract folks to a rural life.

Where did all the tubies go? Constructing a Golden Calf
Hi RATs!
Oh, uh, Jute, I just got a CPAP machine and am sleeping it on ... What is all this tubie business? We have wandered far afield from thermionic joys. I am listening to an SS contrivance from McIntosh, I bought it on Ebay and shipped it home for a rebuild, I am too old to dare freshen a three legged fuse, nor its neighbors. It is a gift to the kid. He may accept thermionic conversion, one day, but this gives his ear good vibes in the interim. Or interegnum, it he persists ... he married a beautiful Catholic, the Earth spins ... Sounds good enough. Not the same as tubes, but, decent. We train ourselves to hear anomolies in the sound and then scream foul. Silly bitch hi-fi martyrs. Bit silly, really. Home audio is a desperate pleasure at best. Often it teaches only disgust and fear. Hoping spring arrives and you are taken by unforseen passion. It is pleasant enough here, but the only news is sleep. Go figure. Happy Ears! Al |

Where did all the tubies go?
Andre Jute crawled out from under a rock and crossposted to uk.rec.audio:
I go away for a couple of weeks to do bike electronics This must be a new definition of 'do,' meaning to buy a complete solution from Shimano and get the local bike shop to fit it. Of course, suspension is pointless on a road bike as, if set up correctly, the legs act as perfect shock absorbers. Things may be different if you are stupid enough to ride a Dutch town bicycle. -- Eiron |

Ride tall. Andre Jute Trick-cyclist No, you still cannot convince me to use all that electronica al junka on de bicycle. And I know what gear automatically to ride with. I have the two change levers on the down tubes still but sonner or later I will wear out all the ancient 1987 Shimano 600 stuff, and need at least new rear cluster, chain, and perhaps I get an index changer for the handlebars so gears will be easier to change, and less clunky; its always a bother to have to remember to change gear before stopping at lights or intersection so you can start off fast to get across traffic almost constantly coming at you. I have 753 and 953 framed bikes, and weight is what the racing standards were in 1990. Last time I fell off, the frame kinda bounced, but didn't bend, all was well, maybe I have done about 50,000km on that bike. Certainly 7,000km since last July. It hasn't been bad, but then not as interesting if i'd done that distance across Russia, although had I attempted that I might well be a ghost, long since having been run down by a Vodka soaked lorry driver. I didn't think bikes got all that much lighter once you go away from a good steel tube frame. Who cares? the weight only slows you up hills, and its the man weight, age and condition that controls hill speeds. Having a bike 2Kg lighter with 30 gear speeds won't make much difference to the time it takes around town. There's a hill that rises about 180M in 3kms across town I often ride, and I used to do it in about 12minutes and with 48 x 16 gears in 1990. Last July I strugged with a 23 rear cog, but after losing weight and gaining power I now use the 17, and maybe I take 15minutes, I don't bother timing myself. But I still catch and pass many younger riders, while remaining comfortable at what seems about the same as ever at about 140 max. One day a young dude who I overtook near the top stopped for a chat at the top. He was 20, but hadn't ridden much since emigrating here to Oz. He'd bought $20 bike at a garage sale. On the way down the hill, we rolled most of the way and his speed remained the same as mine, despite his fatter tyres and not so good machine. Physics does not change for those who spend more on lightweight gear. Some old banger with 32mm tyres will roll just as easy as someone with the latest 20mm tyres. Its a myth that lighter wheels are lot faster. Research on the web showed me how little wheel weight mattered, especially at my age and power and at low average speeds I am only capable of. I just do not need a computer to decide what gear I should use. Most of the climb is done not sitting down.. A kilo here or there is nothing, and I'm 77Kg, heavy and tall for a cyclist, so I need a good solid frame, and of course some 60Kg shorter person will have a lighter bike. I once saw a girl out on a really small frame, and 26" wheels with 20mm tyres, and her bike would have been very light, but its ratio to her own weight may not have been much better than with mine. She had no trouble staying up with the bunch she was in who were all mainly young men under 40. I'll never be an Indurain on hills, and when I have gone out on early mornings when the keener young athletes are riding, I get passed and it makes me feel very slow. But all those young guys would be passed by others of elite standing, and rare it is that I ever am around when the guys are out from the Australian Institute of Sport. They move like greased lightning.... Their Oz headquarters are only a few Km away. It just feels good being alive and riding rather than so old and decrepit that i cannot. A few ppl here are riding recumbent bikes. I mainly pass these guys real easy anywhere, despite their reputation for being quicker than an upright. Only once did some 30 yr old manage to pull away from me on a flat section of road one day. Heck, I was giving him a 29year start advantage. Out on the road they are real dangerous I think. You don't notice them so easily in a car. Lying down to ride does not impress me, although if I wanted to do a landspeed record across salt flats it could be the way to go. I quite like swimming now as well, and regret not spending the extra $3,000 to have made my pool 4M longer back in 1983. Soon the weather will be cold, and I'll be off to the local public 50M indoor heated pool, and that will be a nice change until september when my pool will be back up to a swimable temperature. But in the larger pool technique with water can be improved. I can stay all day for $5 at such a place, and in winter numbers are down, and although a pool is a bit claustrophobic, it is another world.

Where did all the tubies go? Constructing a Golden Calf
tubegarden wrote: Hi RATs! Oh, uh, Jute, I just got a CPAP machine and am sleeping it on ... What is a CPAP machine. Did you DIY it? What is all this tubie business? We have wandered far afield from thermionic joys. I am listening to an SS contrivance from McIntosh, Most of us listen to solid state all the time. What do you think a CD player is? I also have a reliable, solid Quad 405 Mk II power amp and a solid, reliable full-featured (mono switch, anyone? -- very useful for DIY in the rest of the chain) Quad 34 control amp sitting permanently at my left hand. The tube amp de jour stands on top of or beside that lot. Right now I'm listening to Stax headphones via a (horrors) bought silicon amp; it is actually excellent. I designed and built a nice octal tube OTL to drive my Stax but that is now in Japan (all the good audio gear migrates East -- even the Quad II set I'm keeping for my old age was repatriated from Japan) and I got distracted from building the revised version by bicycling matters. I have a row of related designs to drive electrostatic earphones but you can see in this thread why I can't be bothered to publish them and discuss them on RAT. Too many mindless little scumbags sitting around without any intention of sharing information and goodwill, merely waiting for someone to fail so they can gloat. One has to wonder about the quality of their lives -- but not for long; they are depressingly common. I bought it on Ebay and shipped it home for a rebuild, I am too old to dare freshen a three legged fuse, nor its neighbors. That reminds me. I have a Velleman Digital Preamp that my boy started work on but lost interest in after fitting a handfull of parts. I put it aside to complete later but a few years later my eyes and patience are not up to soldering that many tiny joints. You want it, Sander, it's yours for the postage. It is a gift to the kid. He may accept thermionic conversion, one day, but this gives his ear good vibes in the interim. Or interegnum, it he persists ... he married a beautiful Catholic, the Earth spins ... Still? Good God, what shocking news from Phoenix, Father. Sounds good enough. Not the same as tubes, but, decent. We train ourselves to hear anomolies in the sound and then scream foul. Silly bitch hi-fi martyrs. Actually, one of the very worst amps that I ever heard is a Leak Stereo 30 Plus, an early silicon amp. You'd think with Harold Leak's experience in building excellent tube amps... But no, it is utmost crap. I stripped it out to turn the plugs, sockets and switches into a control center for comparison testing of review gear and DIY builds. It's in photos in my reviews in Glass Audio, if you care all that much for late 50's British "styling" -- buttons all over the facia, zero ergonomics, zero integration. Still, it save me drilling and folding a box. Bit silly, really. Home audio is a desperate pleasure at best. Often it teaches only disgust and fear. You may be taking a very long time to die, Al, but I'm only about two thirds through my life and I'm not an audiophile (try this test: I can't even begin to count my discs, and they are certainly worth more than even my excess of plutocratic audio gear). I'm listening to my first box of Haendel, about 250-300 discs, and hearing only the soaring joy (if Haendel feared the eternal fire, he certainly hid it well), and I'm riding in the spring saying hallo to the animals I know in the countryside, or at least their offspring. Unfortunately my pike, a ferociously hungry fish, which lived in a culvert I often sit on to eat my lunch, appears to have migrated to a fatter stream or to have died. Still, another will come along. My herons are now such a flock, I can no longer tell them apart even with the aid of a long lens. You'll enjoy this. I'm sitting on a bridge, hard at work on my fitness, when some old chappie stumbles past, fists pumping 2rpm below his knees, bent over so low you can almost imagine him disappearing slowly into the road until nothing but the illusion of his passing remains. In these parts you make a greeting when you meet people on the road (blow-ins, foreigners and suchlike are the ones who don't greet you even from their cars, a few fingers raised from the wheel being considered polite). So I said to this old chappie, four klicks from town, "You will surely live to be ninety, sir," and he snapped right back, "I'm already over ninety, sonny." Hoping spring arrives and you are taken by unforseen passion. It is pleasant enough here, but the only news is sleep. See above. I'll publish a photo essay of one of my rides; it's sitting on my desktop awaiting formatting as soon as I finish coresponding. (Sure, I can spell correspondent. I like the pun on unforeseen passion better.) Go figure. No math, if you don't mind. Computer models are good, and a tame engineer chained under the table who gets no food until he finishes my math. The whole point about intelligence is that it can be used to invent labour-saving devices. Happy Ears! Al Slainte!

First, I consider what control is desirable which is a nice detour through physics. A bike has some very, very odd handling phenomena, did you know? Clearly not. Then I consider what is achievable. Then I make an outline design from standard parts out of the RS and Farnell catalogues. Then I price building a prototype. When I come out of intensive care, I buy the groupset from Shimano. It does everything I though necessary, and a bit besides (I don't see the point of rear suspension except for dirtjumpers). You of course, ride a common or garden "road" bike you bought in a shop, or more likely second hand from someone who saw you coming, and preyed on you fashion-victim desire to belong to a group. But you feel adequate to the task of sneering at someone who has curiosity and the energy to inform himself and then to act on the information. Congratulions, Eiron, for letting your psyche hang out in public. What will you expose next? and get the local bike shop to fit it. My bike mechanic is nearly eighty. I just let him do the heavy lifting, bending, fiddly work in impossible places while hanging by his knees from the rafters, suchlike. Clean, light assembly of new parts I always graciously undertake myself, if flattered in advance and overpaid for it in proportion to my position in the food chain. It's a good choice to have. Let me give you a tip, Eiron: Always wear gloves, then the grease cannot get under your fingernails. You'll never get a woman with hands like yours. Of course, suspension is pointless on a road bike as, if set up correctly, the legs act as perfect shock absorbers. Do you really think so? I thought you claimed to be an "engineer". Oh well, perhaps at your school for jumped-technicians the teachers weren't allowed to fail the idiots for fear of socially disadvantaging them. Here, I'll give you another tip: what marks you out as a fashion victim is your axiomatic assumption, when I say "bike" that I'm talking about a "road" bike (for the rest of you, by that Eiron means a racing bike with drop handles and an excruciating nut-crusher of a seat). When I say "bike", I don't mean an implement advertising persuaded me would improve my image, I mean a device tailored specifically in the smallest detail to my comfort and intended use. The most important person in my cycling universe is not Lance Armstrong, it is me. Things may be different if you are stupid enough to ride a Dutch town bicycle. You can't imagine how different, Eiron. And it is because of your public failure of imagination that I shan't bother to explain and you will learn nothing. Yet again. But, while you wallow in your ignorance, you might consider whether it is statistically likely that millions of people who cycle every day in Europe can be "stupid" while you, Eiron, alone are right. Now that's a giggle for which I don't mind doing the math! -- Eiron Unsigned out of contempt |

Where did all the tubies go?
Seems to me the good tubies went cycling and swimming and built a pre-
amp and a headphone amp and plotted a SET (1), while the wannabes and trolls and silicon slime sat around waiting for someone to build something so they could drain the glee from his hobby. What despicable people they are! Andre Jute Scum is as scum does (1) There was a time when the projects in progress by RATs required more than the fingers of one hand to count, when the actual makers of stuff outnumbered the pondscum 30:1. Patrick Turner wrote: Andre Jute wrote: Patrick Turner wrote: Andre Jute wrote: That braying ass Eeyore, aka Graham Stevenson, wrote: Andre Jute wrote: I go away for a couple of weeks to do bike electronics Bwahahahahahahahaha ! Bike ELECTRONICS eh ? Graham How typical of you, Poopie, to sneer at what you know nothing about, and lack the brains to understand when it is explained to you. My latest bike has adaptive suspension, automatically hard when going slowly or going up hills to save pedalling energy for forward motion, soft when going quickly for comfort. It has electrically changed gears, also adaptive in 24 programs to the rider's effort, related to road and pedalling speed and so on. When I stop, the gears change automatically to put me in the right gear for starting off again, and the suspension is automatically set to hard so I don't waste energy compressing the suspension. The lights switch on automatically when it is dark and the bike is moving. And off again automatically, of course. Why don't you try moving into the 21st century, Poopie? Who knows, you might like it. This is 2007, sonny; set your clock forward. Gee Andre, I am a far too determined a minimalist to want a bicycle with all the bells and whistles you have refered to above, and in addition to those I nominated for the serious sportsman in another post. Yes, I know what you mean. I'm Calvinist, so I'm by birth and destination and training and inclination a minimalist too; hedonism is a hard-acquired taste. But I already had a bike with hub gears and front suspension and other luxuries like splash guards and a plush seat, so the extra weight of the motor to change the gears and the computer to control it all and the display unit isn't all that much, because it is all lightweight stuff and you're throwing off a cast/ forged rotary control. In addition or, rather, in subtraction, I am also designing a stainless steel frame that will be lighter than the thick ali of my original hub gear Gazelle Toulouse by many kilo, and lighter even by a kilo or so than the Trek ali chassis I currently have the electronic gear on. All in all, the electronic bike will be about 6 or 7 kilo, possibly as much as 15 pounds, lighter than the old one... Okay, so some people have entire racing bikes that weigh that much; so what -- I'm not racing, I'm taking in the scenery or talking, taking social rides. The less I have on the bike, the better. So I clean it sometimes. Clean it? You're joking, of course. I used to drive really filthy Porsche (in sunshine yellow, so the filth would really stand out), and once threatened to fire a driver who insisted on washing and polishing the Bentley. My experience is that people think that anyone who can drive a car that filthy will also not care if it is crushed a little against their shining, polished pride and joy, and consequently are in a real rush to get the hell out of my way. I don't wash my bike either. On the Gazelle I sit taller than the drivers of Range Rovers, bend to look them in the eye, then cut them off in traffic with impunity. If my bike were clean, they'd cut me off; most of those buggers, and all their wives, have no idea at all about where the corners of their landyacht are. They'd hit me for sure if they saw a clean bike and thought I cared, and consequently cut me off. I dunno any shiela across town who's worth rooting after hours, so I don't need lights. When it rains, I get wet. I have a cycling cloak that I imported from the Netherlands but it gets very little use. Even my yellow paclite jacket is used more often as a windbreak than to keep me dry. My rides are rarely so long or so urgent that I can't shelter from the worst of the rain under a tree, or can't reach home and a hot bath even in persistent rain before the cold reaches the marrow. The persistent drizzle we in Ireland call "a soft day" has long since ceased to bother me. What really hurts is hail; we have hail perhaps twice a year and each time I am caught in it. Mudguards don't help much, and electronics have a bad habit of not working in the damp. Is that right? I'll have to take your word for it. Only electronics I ever had that refused to work was a fuse panel in my wife's Volvo estate. Made by Lucas, Prince of Darkness, of course. Worse than the spaghetti merchants at Magneto Marelli. No amount of electonics make hills any easier to ride over, Rubbish. I ride up the hills without thinking about which gear to be in, without wasting time and energy being in the wrong gear, and trying to remember whether the 31 gear inch ratio is two up at the front and four down at the back or some other forgotten combo. All I do is punch the button under my right thumb twice to drop the gearbox mode from sport through normal into little old lady mode, which is good for hills. The sports mode won't let me use a gear lower than second, and the normal mode is what I already have on another bike, which is just the eight hub gears at my normal energy expenditure -- I dinna spend the money to do the same thing! But the little old lady mode (Shimano calls it L for leisure) lowers the expected rate of work so that on a familiar hill my pulse rate was 30bpm lower than when I went up there the previous week on a manual bike. The ascent was clearly easier. That the electronics automatically harden or lock out the suspension when you're travelling slowly or steeply uphill also helps, and probably substantially, but I can't see how one would reliably quantify the contribution of the adaptive suspension. and they don't slow headwinds, which should all be blowing slower because countless windmills have been erected all over the country to stop greenhouse emissions, and ruin the tranquil views that attract folks to a rural life. They don't put those up near me. I made a phone call to the flat of the relevant pol's mistress to remind him that about 440AD my ancestors ate his ancestors' livers, a tradition I might just resurrect; the windmills got "reevaluated", code for cancelled. Windmills don't work, will never pay for themselves, aren't as silent as nuclear power. The only good thing about windmills is that they kill a lot of crows and seagulls; on the other hand, they also kill worthwhile birds like swans and geese and ducks. Together with some environmentalists I was walking with, I cooked and ate a swan that a windmill killed; it was as tough as badly hung beef even though it smelled high enough... Patrick Turner. Ride tall. Andre Jute Trick-cyclist No, you still cannot convince me to use all that electronica al junka on de bicycle. And I know what gear automatically to ride with. I have the two change levers on the down tubes still but sonner or later I will wear out all the ancient 1987 Shimano 600 stuff, and need at least new rear cluster, chain, and perhaps I get an index changer for the handlebars so gears will be easier to change, and less clunky; its always a bother to have to remember to change gear before stopping at lights or intersection so you can start off fast to get across traffic almost constantly coming at you. I have 753 and 953 framed bikes, and weight is what the racing standards were in 1990. Last time I fell off, the frame kinda bounced, but didn't bend, all was well, maybe I have done about 50,000km on that bike. Certainly 7,000km since last July. It hasn't been bad, but then not as interesting if i'd done that distance across Russia, although had I attempted that I might well be a ghost, long since having been run down by a Vodka soaked lorry driver. I didn't think bikes got all that much lighter once you go away from a good steel tube frame. Who cares? the weight only slows you up hills, and its the man weight, age and condition that controls hill speeds. Having a bike 2Kg lighter with 30 gear speeds won't make much difference to the time it takes around town. There's a hill that rises about 180M in 3kms across town I often ride, and I used to do it in about 12minutes and with 48 x 16 gears in 1990. Last July I strugged with a 23 rear cog, but after losing weight and gaining power I now use the 17, and maybe I take 15minutes, I don't bother timing myself. But I still catch and pass many younger riders, while remaining comfortable at what seems about the same as ever at about 140 max. One day a young dude who I overtook near the top stopped for a chat at the top. He was 20, but hadn't ridden much since emigrating here to Oz. He'd bought $20 bike at a garage sale. On the way down the hill, we rolled most of the way and his speed remained the same as mine, despite his fatter tyres and not so good machine. Physics does not change for those who spend more on lightweight gear. Some old banger with 32mm tyres will roll just as easy as someone with the latest 20mm tyres. Its a myth that lighter wheels are lot faster. Research on the web showed me how little wheel weight mattered, especially at my age and power and at low average speeds I am only capable of. I just do not need a computer to decide what gear I should use. Most of the climb is done not sitting down.. A kilo here or there is nothing, and I'm 77Kg, heavy and tall for a cyclist, so I need a good solid frame, and of course some 60Kg shorter person will have a lighter bike. I once saw a girl out on a really small frame, and 26" wheels with 20mm tyres, and her bike would have been very light, but its ratio to her own weight may not have been much better than with mine. She had no trouble staying up with the bunch she was in who were all mainly young men under 40. I'll never be an Indurain on hills, and when I have gone out on early mornings when the keener young athletes are riding, I get passed and it makes me feel very slow. But all those young guys would be passed by others of elite standing, and rare it is that I ever am around when the guys are out from the Australian Institute of Sport. They move like greased lightning.... Their Oz headquarters are only a few Km away. It just feels good being alive and riding rather than so old and decrepit that i cannot. A few ppl here are riding recumbent bikes. I mainly pass these guys real easy anywhere, despite their reputation for being quicker than an upright. Only once did some 30 yr old manage to pull away from me on a flat section of road one day. Heck, I was giving him a 29year start advantage. Out on the road they are real dangerous I think. You don't notice them so easily in a car. Lying down to ride does not impress me, although if I wanted to do a landspeed record across salt flats it could be the way to go. I quite like swimming now as well, and regret not spending the extra $3,000 to have made my pool 4M longer back in 1983. Soon the weather will be cold, and I'll be off to the local public 50M indoor heated pool, and that will be a nice change until september when my pool will be back up to a swimable temperature. But in the larger pool technique with water can be improved. I can stay all day for $5 at such a place, and in winter numbers are down, and although a pool is a bit claustrophobic, it is another world. Patrick Turner. ****** And here is what I wrote originally, from which you took your dumb soundbite to sneer at: ****** Andy Evans is right. There used to be real tube talk on RAT. Now there's a bunch of tacky radio restorers and fools with a dire self- image shortfall. Yech! I go away for a couple of weeks to do bike electronics and return to find hardly anything worth reading and only one intelligent question -- from West -- worth answering. The same people are still beating internal NFB in triodes to death with pinpricks. Sheesh, fellers, either you believe the observable anomalies in triode results is caused by invisible NFB, or you conclude that pentodes are naturally, permanently and irredeemably (nice word on Easter Sunday) inferior. But neither party will convince the other. What a waste of time.

Starved filaments

I know you have mentioned Steve Bench in relation to this, but I wondered, have you done any measurement of the actual effect of running the fill at a 4% reduced voltage? -- Nick The filaments in my T39 Ultrafi design (see my netsite, URL under my sig) are closer to 8 per cent reduced from book spec. It is essential to anyone else's understanding of this discussion that you view the T39 Ultrafi circuit and also read the Starved Filament document on Steve Bench's site. My associate Bill May made some tests with starved filaments. I've never made much of a song and dance about it because a) we didn't find anything Steve Bench isn't telling everyone who is interested, and b) that sort of thing is simply too subtle to discuss with the soundbiters hovering on RAT to ruin every thread and drain everyone's glee in this hobby with their luddite sneering and jeering and their sullen incomprehension of what really matters. What happens with starved filaments is that the distortion is lowered, the odd and higher harmonics more than the second, always a very good thing. The mechanism for this is that the Eb-Ia-Eg transfer curve is flattened, much more at the extremities than in the middle. It is as if a fat current source has been put in the circuit, making the response so much more constant throughout its range. Like I said, a subtle effect, and damned difficult to see graphically if you start with tubes already very linear like a 300B or an 845. Either Steve knew this or just got lucky with the tubes he chose to experiment with, which have obviously visible beneficial effects from starved filaments when you compare the curves he took with starved filaments to the official fullspec curves. I like a very silent amp and am not afraid to pay a price for it in power not extracted from the tube, so I do starved fils even with 300B, even though I know that the effect, at margins to which I will never drive the tube, will not be huge on such an already very silent tube. All those little margins of silence add up to the refinement that lesser designers must seek in negative feedback. Of course, it also means that the overload characteristic of my amp is extended, and made more refined. Steve Bench is a great benefactor to DIY tube audio. The other idea I got from Steve that is incorporated in my T39 is the four separate grid resistors on the 417A. Questions were raised at one point about starved fils leading to contaminated cathodes. I have never seen such results and those pontificating hadn't either, though that didn't stop them wittering on portentiously. HTH.
