Why is Poopie two cheeks short of being an asshole?
Why is Poopie (1) two cheeks short of being an asshole?
It can't be only because he's old and bitter. It can't be only because he is an incompetent. It can't be only because he is a braggart. It can't be only because he is ugly. It can't be only because he is a fascist and a hypocrite. There's gotta be a bigger reason than even this collection of petty failings to create such a petty man. So why is Poopie two cheeks short of being an asshole? --A public service riddle by Andre Jute (1) Graham Stevenson aka "Eeyore" , who claims to be an electronics engineer and designer but who is known to earn his living micing tenthrate pub acts. |

845 dreams was: Why is Poopie two cheeks short of being an asshole?
Hi RATs!
OK, I got a power transformer which will drive an 845 without a bunch of voltage doublers, triplers, whatever 105/115/125 primary 1400/700 secondary. Model is 901367. I am going to use a choke input PS filter, with a 100uF 2000V oil cap. Maybe more, will listen and decide. 866 MV (mercury vapor) rectifiers. Initial OPT will be two One-Electron ubt-2 with primaries in series and secondaries in parallel. Each primary will have a parallel resistor to reduce ringing and other boisterous behavior. DCR of R to be between 5 and 10X the primary Z. I love this techno talk The DCR of the PT secondary is 38 ohms. Same as the like sized (BIG) choke I am going to use Happy Ears! Al |

You got it from other Americans who spread the lie as a political manoeuver. In other words, Poopie, you're a tiny cog in an American political machine. And where do you think you got the idea from that "9/11 was a good thing for the US", why, you got it from other Americans making a political point in the hope of persuading Mr Bush to spend even more on homeland security. In other words, Poopie, you're a loud tool for the military-industrial complex; you might remember that even President Eisenhower, who when he was a general saved Britain from the Germans, was agin the military industrial complex -- but now you're helping them! Even your "nuclear inferno", Americans, for the consumption of, is an American idea first mouthed by Jerry Rubin one night when he was drunk. Comedians of the Lenny Bruce persuasion made jokes about it, but respectable comedians too at private Manhattan parties. What you consume, what you wear, what you think, dear Poopie, is Out of America. Even your hero, Osama, is an American stooge just like you -- he was sent to Afghanistan to stiffen the backbones of the mullahs in the Taliban against the Russian invaders a generation ago. He just turned traitor because, with the Soviet Union imploded on Reagan's clever SDI bluff, there was no one else for poor old Osama to vent his adrenaline on. He fancied himself as a sort of richer, better-spoken Lawrence of Arabia, didn't want to give up such an attractive image of himself, and turned on the only enemy available. It's an old story. So, coming or going, you're ****ed in your mind and every other way by American dicks. Lie back and enjoy. Nobody pays as well as the Americans... *** Of course, you are too hysterical to grasp my rigorous logic, but don't worry, dear boy, I'm not giving it for your benefit -- personally, I would probably be indifferent if you died of the syphilis that clearly has already driven you demented -- but as an entertaining latterday example of what Lenin -- another syphilitic -- called "useful fools".

Does this mean a full wave bridge or two half wave rectifiers? The former puts the 845's into their really linear region; the latter is a supply of about 600 volts. Initial OPT will be two One-Electron ubt-2 with primaries in series and secondaries in parallel. Each primary will have a parallel resistor to reduce ringing and other boisterous behavior. DCR of R to be between 5 and 10X the primary Z. A SE class A amplifier doesn't cross the zero current line in its working range, so damping may not matter enough to bother. Can't hurt, I guess. Two comments based on my similar project several years back: First, I found that not too long after I finished the construction (1994) I got too old to pick it up (120+ pounds) for modifications. There really isn't a good technical solution for this; the power supply is so dangerous that it needs to be in the same chassis as the signal amplifiers. Maybe... Second, the issue of output transformers. I used the British-made Audio Notes, cheap-but-cheerful choice of the time. Note that primary inductance doesn't scale the same with turns when connecting two transformers in series; it only adds linearly. These days, I'd talk to Patrick, who really knows his stuff, about a pair of really good transformers. They're the real bottleneck of any tube amplifier. Even the best is still just good enough. Very good fortune, and much thanks, as always, Chris Hornbeck |

A single choke plus cap isn't nearly enough hum filtering. Even another section of each is just barely enough. All power supply hum appears across the OPT primary in single-ended designs.

Ambitious bugger, aren't you? I love 845 but they do have some application problems. One is high drive requirement, 150V peak or better to do the job right for c20 big watts. The next one is high voltage at the plate. You can operate 845 from about 500V up, and the Japanese do, or did while the fad lasted, and I tried it and sounded like **** unless the amp was very much restricted to a sub-300B output, at which it sounded somehow caged. Linearity, which is what an 845 is really about (with warmth) starts at about 850V but the sweet spots I have found are 960 and 1040V -- yeah, I know, you don't think much of other people's sweet spots, but wait until you start turning over a 100lb minimum amp several times a day to resolder leads: you'll soon see the merit of picking a good operating point before you start. The final big problem of 845 is that they are in bed with Miller's mother; you need 20mA on the driver plate to kill that capacitance or it will kill your HF stone dead. A good way to handle the high drive requirement and the high driver requirement in one swoop is to use a power tube for a driver. I liked 417A300B845. Terribly predictable. Some people have taste and some don't. Trioded EL34 just about make the cut. I am going to use a choke input PS filter, with a 100uF 2000V oil cap. Maybe more, will listen and decide. What size is a 100uF 2000V oil cap? You'd do better with two sections or even three each of 10H and as little 18 or 20uF (I worked it out once, and then got the nearest available value) to clear about 30dB under the fundamental. Patrick probably has 845 smoothing at his fingertips as he recently built one. 866 MV (mercury vapor) rectifiers. A bridge of those is a lot of filament heat, and a lot of filament heaters, and a lot of voltage dropped. Try a Graetz bridge instead. You need two tube diodes and two silicon diodes, and the tube diodes block the noise of the silicon. There's a sample he http://members.lycos.co.uk/fiultra/T...trafi-crct.jpg Sander probably knows the US equivalent of the BY228--which I was told in a private letter by someone that is a strictly European part number --and whether the direct sub is rated for the more demanding application or whether you need to go up the range. Initial OPT will be two One-Electron ubt-2 with primaries in series and secondaries in parallel. You won't get the bass you're hoping for, if you are -- you might be too smart already. The advantage of two transformers in series is never a doubling; at best it is a gain of 40% and I've seen as little as 11% when I ran two interstage transformers in series and series-parallel in an effort to improve current capability. Each primary will have a parallel resistor to reduce ringing and other boisterous behavior. Why? Is this amp not SE? Let Patrick calculate the optimum damping, satisfy yourself, if you're obsessive, with about a fourth or a fifth that much, and don't give it another thought. It dinna matter in SE amps. Very low damping factors are for fashion victims and impressionables. A real man's tube amp turns down the frequency extremes without the said man having to take his hands off his woman to reach for the attenuator. And while we're on the subject, attenuator is a weasel word. It's a volume *control*. (I also notice far too many police "services"; it's a police *force* or it is useless for its declared purpose.) DCR of R to be between 5 and 10X the primary Z. I love this techno talk Eh? We're not talking about cars, just about valves. Valves don't have complicated technicalities. Why, even Arnie thinks he can do valves! The DCR of the PT secondary is 38 ohms. Same as the like sized (BIG) choke I am going to use The reason I broke up my last 845, and my even bigger Millennium's End 75W SE Svet 572-xx was that they weighed too much to handle without a block and tackle. The solution is to break the amp across chasses but even so the component parts can be damnably heavy. My solution to not having too many high voltage components flying around, and limiting the voltage as well as the number of umbilical leads, was to build two amps each with their own on-board power supply. The power amp just had the power tube and its associated bits, the other chassis had the input and driver tubes, the driver being linked to a good quality output transformer (Lundahl cut-C core) so that it was a complete amp which at the flick of switch (or two) could turn the OPT primary into a choke on the 300B plate and link its output capacitively via an umbilical to the power section. Hardly ideal but safer than 1200V on what could in an accident turn into flying leads spraying lethal electricity in your direction... Happy Ears! Al Good luck. Andre Jute |

Good linear bottles, but they require feedback back around from their anodes if using unbypassed cathode resistors, which I'd have insisted on, to give a low enough drive impedance. These days I might start with triode connected EL84's with battery or maybe "fixed" bias. There's really no such thang as a two-stage 845 amplifier, so it's a balancing act and a judgement call. Hardly ideal but safer than 1200V on what could in an accident turn into flying leads spraying lethal electricity in your direction... This is a really important point. Our own skunky asses are pretty much disposable, but we need to *always* keep foremost in our minds that friends, loved ones, grandchildren, pets, who knows, can and some day *will* get into our widgets. They matter, so SAFETY first and last. Much thanks, as always, Chris Hornbeck |

845 dreams

The final big problem of 845 is that they are in bed with Miller's mother; you need 20mA on the driver plate to kill that capacitance or it will kill your HF stone dead. The 845 needs a driving tube with 150Vrms capability. This is easily achieved with choke loading an EL34 in triode. The ideal op point imho is Ea = 1,100V, Ia = 65mA, RL = 12k. The Miller C isn't all that high because the 845 voltage gain is below 5, but nevertheless the driver EL34 should have Ea = 400V, Ia = 25mA. If CR coupling is used from the '34 anode to 845grid, the biasing resistance of say 33k is the main load seen by the EL34 since the choke which should be over 35H will have a huge Z for most of the AF band which won't cause much phase shift/roll off because the '34 ra = about 1.3k. The EL34 has a gain of about 8, so it will need about 16vrms of grid drive which could come from a bootstrapped follower stage using 6SN7, or plain common cathode stage with both halves paralleled but with a CCS load for the dc, so that the '34 grid bias resistor is the only load seen by the '34, and thd is thus minimal. A good way to handle the high drive requirement and the high driver requirement in one swoop is to use a power tube for a driver. I liked 417A300B845. Terribly predictable. Some people have taste and some don't. Trioded EL34 just about make the cut. I am going to use a choke input PS filter, with a 100uF 2000V oil cap. Maybe more, will listen and decide.

You'd do better with two sections or even three each of 10H and as little 18 or 20uF (I worked it out once, and then got the nearest available value) to clear about 30dB under the fundamental. Patrick probably has 845 smoothing at his fingertips as he recently built one. I'm using plenty of seriesed 470uF x 400V rated caps and one choke of about 10H but there are two stacked voltage doublers to get the wanted voltage including enough for cathode biasing. Its more complex than this because I have set up the 845 so there is fixed grid bias at -500V, then cathodes are at about -330V, and so anodes and the primary winding are at +770V, which is less likely to ever arc to the earthy bits such as the secondary of the OPT than if I had Ea of +1,100V plus cathode bias of +170V for a total of +1,270V applied to the OPT primary. 866 MV (mercury vapor) rectifiers. A bridge of those is a lot of filament heat, and a lot of filament heaters, and a lot of voltage dropped. Try a Graetz bridge instead. You need two tube diodes and two silicon diodes, and the tube diodes block the noise of the silicon.

The advantage of two transformers in series is never a doubling; at best it is a gain of 40% and I've seen as little as 11% when I ran two interstage transformers in series and series-parallel in an effort to improve current capability. It depends on winding losses of the OPT. If there are two primaries each giving 3k reflected Z to whatever secondary, then series of two such windings is 12k, and the inductance is also 4 times the single P or two in parallel. Each primary will have a parallel resistor to reduce ringing and other boisterous behavior. Why? Is this amp not SE? Let Patrick calculate the optimum damping, satisfy yourself, if you're obsessive, with about a fourth or a fifth that much, and don't give it another thought. It dinna matter in SE amps. Very low damping factors are for fashion victims and impressionables. A real man's tube amp turns down the frequency extremes without the said man having to take his hands off his woman to reach for the attenuator. And while we're on the subject, attenuator is a weasel word. It's a volume *control*. (I also notice far too many police "services"; it's a police *force* or it is useless for its declared purpose.) The 845 is a low Ra triode so there is plenty of natural damping of the parasitic effects of OPT leakage inductances and shunt capacitance. The latter capacitance is your main enemy, since with Ra = 1.8k for 845, then 0.003uF looking into the P end of the winding means - 3dB will be 29kHz. With RL = 12k, we want Z Lp to be = RL at 20Hz or better. So Lp should be 95H, which is asking a heck of a lot from what must be a gapped and large OPT. I have a pair of 845 in parallel, so I need only 45H. The RL of 12k plus the Lp means that the load become partially reactive and equal to 8.5k at 20Hz, so its impossible to maintain a flat response down to 20Hz from say 1 kHz without clippinj commencing visibly at say 35Hz on the CRO. So a lack of available Lp means that full power bw is limited. But we we just never build 845 amps to be expected to give a dead flat undistorted full power response down to 20Hz. We will never run the amps that hard. At low levels of say 2 watts instead of 20 watts the load value reduction dues to Lp shunting RL does nothing to reduce bass response of to cause noticeable distortions. This is because the -3dB point in the response occurs due to the ZLp shunting both the 12k and Ra in parallel. This is about 1.6k, and so Lp could be 18H for a -3db point of 14Hz. Saturation and operating dc flux densities and max ac flux densities are issues all needing careful thought and the only way to avoid such issues is to use a pair of 50H chokes in series for the DC supply to the tube, then capacitor couple a "normal" ungapped OPT to the anode with say 47uF which is rated at 2,000V, so a few caps in series may need to be used. DCR of R to be between 5 and 10X the primary Z. I love this techno talk Eh? We're not talking about cars, just about valves. Valves don't have complicated technicalities. Why, even Arnie thinks he can do valves! The DCR of the PT secondary is 38 ohms. Same as the like sized (BIG) choke I am going to use I fear a few ppl are not being precise enough about what they propose and I issue a smoke warning. The reason I broke up my last 845, and my even bigger Millennium's End 75W SE Svet 572-xx was that they weighed too much to handle without a block and tackle.

Hardly ideal but safer than 1200V on what could in an accident turn into flying leads spraying lethal electricity in your direction... Monobloc for 845 is a must because of weight, and I don't recommend HV umbilical cables. I'm using KR Audio 845 tubes. Try going to the Oz importer for KR products at http://www.vares.com.au Click on the link to KR amps which have their tubes within. Both the OPT and PT for my latest SET amps with 2 x 845 in parallel have a 70mm stack of 50mm tongue highest quality GOSS. The chokes are not very large and the caps don't weigh much, but then there is the metal work and it all adds up. These are heavy amps for only 45 watts each. But rather nice watts. Patrick Turner.

There's gotta be a bigger reason than even this collection of petty failings to create such a petty man. So why is Poopie two cheeks short of being an asshole? --A public service riddle by Andre Jute (1) Graham Stevenson aka "Eeyore" , who claims to be an electronics engineer and designer but who is known to earn his living micing tenthrate pub acts. What is "micing tenthrate pub acts"? Mr. Jute has, to my utter dismay, perpetrated a near-unpardonable grammatical sin. He has used "micing," a convention in popular circulation among the singularly clueless fader-jocks and other audio industry ****s. I commented on this back in July, 2004 (among other times unfortunately all too numerous) in a post replying to the question of what can and what cannot be considered an acronym. It's a singularly fine rant, and bears repetition. It is again renderered hereinunder, for the edification of the clueless and the gentle correction of Mr. Jute, whose skill with the English language I usually respect. spank (As an aside, I would have hyphenated "tenthrate," but that's hairsplitting. Or hair-splitting, as the case may be. ;-) __________________________________________________ _____ Originally posted to alt.audio.pro.live-sound in July, 2004: Lord Valve Speaketh: As the OLAGOTEFI (Official Lexicographer And Grammarian Of The Entire ****ing Internet [which is in itself an acronym, pronounced oh-LAG-oh-TEFF-ee, minor accent on syllable two, major accent on syllable four]) the Lord must agree. In order for a series of letters to be considered an acronym, it must form a pronounceable word. "FBI" (Fat Boys Institute" and "FOH" (Fat Old Hippie) are not pronounceable words. "Scuba," "radar," "jeep" (the Lord wagers most folks don't know where that one came from, and no fair looking it up) and the like all *started* as abbreviations, but soon thereafter became words due to their prounounceable nature. The more euphonious the construction, the quicker it evolved into common usage as a pronounced non-abbreviation. Part of the present confusion arises from the fact that it is customary (nowadays) to eliminate the periods from the letter groups which are unpronounceable and still considered to be abbreviations. "F.B.I." and "F.O.H." are the technically correct forms for our two examples, and with the inclusion of the periods, no-one attempts to treat them as anything but what they are - unpronounceable abbreviations. In the case of "S.C.U.B.A." (Some Come Up Barely Alive) the transition was understandably swift. It is, in the popular lexicon, a bitchin' fine-sounding word, and great fun to say. Which brings the Lord to one of His pet peeves: Alnico. Why is it that many otherwise highly intelligent audio professionals insist on pronouncing this word "al-KNEE-co"? Please, "everybody does it" is no excuse. Any dictionary you wish to look in (provided it has been compiled by a true lexicographer/etymologyst, and not some smart-ass audio****** fool) will give you the correct pronunciation for this word: "AL (rhymes with 'gal') ni (as in 'nick') coh." Accent on the first syllable, short I, long O. Try it: AL-nick-oh. Alnico. See how it rolls off the tongue when pronounced correctly. This word was formed from the chemical symbols of the three metals which make up the alloy: ALuminum (or ALuminium, for you Limeys), NIckel, and CObalt. Note the word "nickel." If it is customary for you to say "NEE-cull" when pronouncing that word, then fine - you may say "al-KNEE-co." Otherwise, smarten up and say it correctly. And before any of you audio assholes take the Lord to task over this, just remember: next time you hear president Bush (or ex-president Carter, come to think of it, who ought to know better, having been a nuclear power engineer in the Navy) say "NUKE-you-lur," you'll have to keep your mouths shut. And you know you can't do that, so - AL-nick-oh. Don't even get the Lord started on "mic," which by any interpretation of the rules of pronunciation for English must be enunciated as "mick." The downright obstinate use of the ungainly and confusing shortened form of "microphone" leads to embarrasing constructions like "micing" (*must* rhyme with "icing," sorry, shut the **** up) instead of the instantly recognizable and pronounceable "miking." (Rhymes with "hiking" - see how that works?) "Miked." (Rhymes with "hiked.") And "mike" is the proper representation of the abbreviated form of "microphone." I want all of you to do something you've never done befo step away from your monitors and pick up a dictionary. Use a good one, a real one, not one of those "Audio Cyclopedia" bull**** rags. Look up "mic." Look up "miced." And "micing." Did you find 'em ok? No? Now, slowly, carefully...look up "mike." I ****ing told you so. Lord Valve JAFAWAM (Just Another ****in' Asshole With A Modem) |

Chris Hornbeck wrote: On 21 Oct 2006 22:00:21 -0700, "Andre Jute" wrote: A good way to handle the high drive requirement and the high driver requirement in one swoop is to use a power tube for a driver. I liked 417A300B845. Terribly predictable. Some people have taste and some don't. Trioded EL34 just about make the cut. When I built mine, I was a fashion victim and used two paralleled sections of 6SN7. Good linear bottles, but they require feedback back around from their anodes if using unbypassed cathode resistors, which I'd have insisted on, to give a low enough drive impedance. I used to like driving output stages with 6SN7 and I still do. When paralleled, a 6SN7 has Ra = about 5k with 4mA per triode for a total of 8 mA. But for when one wants the best musical dynamics, the EL84 or EL86 or 6AR5 or 6V6 or suchlike power tetrode or pentode is a better driver for anything where there is more than 1 output tube to drive, or the output tube has more than a usual amount of input capacitance. For where you need a high drive voltage ability as well as current ability to give the dynamic accuracy, then EL34 trioded is hard to beat, but some would argue the only appropriate bottle to drive an 845 is a 300B. I may have said a 2A3 would suffice. Using FB around 6SN7 with unbypassed Rk is a possibility, and I assume you mean shunt NFB but then the gain has to be reduced a lot if you want Rout to be low. I don't think a 6SN7 is a sufficiently capable tube to drive an 845 unless you do it like they used to with a 1:2 step up tranny which restricts bw unecesariliy, and so many of those old amps made before WW2 were very short of bw. Local shunt NFB around a 6SN7 to reduce its Ro menas Rin is low, and a pain to drive and its just simpler to use an EL34, with bypassed Rk, because gain will be about 9, and whatever 2H you get will cancel that produced in the output stage, Rout = Ra = 1.3k = low enough, and the input tube need only produce a lowish 16Vrms. The input tube to driver tube interface HF losses are just as important as anywhere else and the Miller effect between an input tube and driving EL34 is probably a worse problem than between EL34 and the 845 or two that one is trying to drive. Then one has to decide if one wants global NFB to smarten up the whole operation, if one sees at all that NFB around SET amps has any rightful place at all. One has to be a bit careful because the two stages of tubes plus OPT cause a rapid phase shift and where open loop gain is above 1.0 and phase shift is 180 degrees, then HF oscillations are possible. In my case the OPT has a 6k:6 OPT ratio ie, ZR = 1,000:1, so the Ra = 1k approx of the two parallel 845 = 1 ohm at the secondary. Adding winding resistance means Rout = approx 1.16 ohms without global NFB. If the 845 is operated at a lower Ea, perhaps 800V, then RL is halved, so the OPT has a ZR of 500:1, so the Rout will be 2.16 ohms instead using the higher Ea, higher RL, and higher ZR possible. But 8 dB of global NFB will reduce Rout by slightly greater than 1/2, widen bw, and lower 2H at a slight penalty of only slightly reducing the 3H and maybe slightly increasing 3,4,5,6,7,8,9H etc. This won't probably matter because the THD without NFB at normal 2 watt levels in a 20 watt SET amp is usually negligable, so the generation of extra high order harmonics due to only slight NFB isn't a worry imho, since the benefits of low Rout are greater than any other negative considerations. These days I might start with triode connected EL84's with battery or maybe "fixed" bias. There's really no such thang as a two-stage 845 amplifier, so it's a balancing act and a judgement call. EL84 don't really like being set up with Ea = 400V, and Ia can only be safely about 15mA for 6 Pda = 6 watts, so a pair in parallel are a lot better. Then the pair have µ = 20, Ra = 1.2k, and will give as good an amount of linearity as an EL34. The load lines will show that one can get 275peak volts swing ( 194Vrms ) with Ea = 400V, Ia = 25mA ( for the two EL84 in parallel ), and RL = 16k. This would appear to be plenty, and Ea could even be lowered to around 350V and you'd still get maybe 160vrms, probably enough for 845. Choke loading is the way to go to avoid having to use a CCS with 400V across it to allow a swing. The choke should be 40+H, so that even at 20Hz the ZL = 5k and the EL84 gain isn't too shunted by thre choke inductance. To get 25mA dc to a pair of EL84 anodes via a resistance means that if the supply is say 800V, and Ea = 420V ( including the cathode bias ), then you need a 15k resistor just for the dc, and then if the following grid bias R = say 33k for ONE 845, the total load = 10.4, and its getting low. The best solution is to have a choke of more than 40H PLUS a 4.7k resistance to the anode, so that even 2Hz there is at least 4.7k dc supply resistance and the gain is hardly altered by the choke inductance and low impedance at 2 Hz, and where phase shift occurs. 40H needs to be the measured inductance at say some low F, say 50Hz, because the permeability falls rapidly above 100Hz. One has to be careful applying inductance formulas, and a choke with 40H at 50Hz won't be 40H at 1 kHz. However, if L = 40H at 50Hz, then ZL = 12.6k, and the effect of this Z in parallel with the 33k and Ra is quite negigible on gain which is approaching µ. The 4.7k series R also helps to keep the RL high enough at LF by isolating the shunting effect of the L and also to isolate the shunting effect of the choke self capacitance at HF. To all those who already have a choke loaded driver stage I would suggest they try an added series R between choke and anode; it widens bw, and increases gain and reduces distortion, all of which is good for the music and FB isn't needed. The Ea required may have to be a little higher than the pure choke loaded case; 25mA across 4.7k = 117V. But in an 845 amp there is no shortage of a high enough anode supply for the driver. Where one wants to use a 211 in lieu of the 845, the drive voltage is about halved, bias voltage is less but then one may wish to operate the SET 211 with class A2, and this means a cathode follower directly coupled to the 211 grid is called for, so one EL84 needs to be devoted to this purpose. Hardly ideal but safer than 1200V on what could in an accident turn into flying leads spraying lethal electricity in your direction... This is a really important point. Our own skunky asses are pretty much disposable, but we need to *always* keep foremost in our minds that friends, loved ones, grandchildren, pets, who knows, can and some day *will* get into our widgets. They matter, so SAFETY first and last. Well, there is HV inside every microwave, and folks were scared of the radiation leakages, but seems we live with that alright. Tube amps with low voltages and no covers over the tubes are about as bad as bare light bulbs with 240V mains, and again, such lights don't kill many. Its amazing amps with 211 and 845 et all have not killed anyone, or not enough to make the authorities at least here in Oz classify such amps as "prescribed articles" which require special NATA lab safety approval before being legal for sale. The amateur radio operators with high power RF amps with 2,500V on their output stages would be a bigger curse if junior gets into grandad's shed and plays around. One guy I know who manufactued and sold lots of amps with 211 transfered the title of the house into his wife's name to avoid anyone snatching his house if he was sued. Not so easy if you ain't married; and can you trust a wife? I might add that PP operation of 845 or 211 is somewhat awesome, not to mention the brute force of 813 wound up on high voltages..... If anyone gets hurt by anything you make, then regardless of whether the safety has been approved by an authority or not, then one is at risk of losing everything in a court case because even if you can proove you made the article properly, a judge or jury will still tend to side with an injured party. In some cases where ppl are hurt its because the owner altered the amp, or proceeded to blatently ignore warnings about tinkering about. But I feel I have to draw the line on umbilical cables carying more than 500V. One has to allow for a PS to fall off a bench and strech and expose live wires, so some means of protection should be added to prevent the PS working if the PS or amp is tipped out of level, a mercury switch is a good thing with SCR that stays latched to cut the mains power, or cause the mains fuse to blow. I was a building contractor for 20 years operating as a sole trader under my own name and took the risk that I may lose everything but it never happened because I took my time, proceeded without haste, built things that were solid and unlikely to ever fail, I avoided accidents, and I never had anyone sue me.

That new medication which had such promise failed after all. It stopped taking that new medication as it missed being the center of attention. However, the post does prove that its arrogance, ignorance, viciousness, inanity and absolute lack of humility are entirely unaffected by the episode. It is also interesting that McCoy, Middius and Morein should be such a tight triumpulcidaete (as there are no men (vir) involved, 'triumvirate' is not appropriate). And each for their apparent singular purpose which is to attack phantoms and/or others who are infinitely more accomplished than themselves. We have McCoy ringing in the sockpuppets, Middius babbling in newspeak, and Morein making assertions without proof or reference. Peter Wieck Wyncote, PA |

Call it 25mA just to be comfortable. A supply voltage of 800 volts is about right. It's not a problem; really. But in an 845 amp there is no shortage of a high enough anode supply for the driver. Yeah, RC coupling is pretty easy. Much thanks, as always, Chris Hornbeck |

I got three each off Ebay 8^) I will drive the 845 with my last homebrew, a trioded 6550C SE. The series ubt-2 will give me 19.2K input Z with 8 ohms paralleled. John Atwood, the transformer's Daddy, recommended the resistor shunts. He sez the low freqs will probably be OK for my 100+dB W/m ehorn. I am treading on fresh ice on the high voltage application. If I survive, I may ghost an App Note ... If I don't I may just ghost. My pal Kavichandra Swami sez I will just start soiling diapers again. Ghost sounds like more fun Suckling was prolly great, but, I just can't remember ... The 866 quad will give me adequate voltage for a cathode biased 845, Steve Bench said that was a good place to start. I have some killer Lambda DC power supplies for both the 866 and 845 filaments. Apache Reclamation is sort of like Nirvana, right here in town Huge supplies cost less than a carton of my wife's cigarettes. I build my homebrews on the bare concrete floor under a big, empty, antique radio phono console. No, I can't move the whole amp. So what! Even when I was healthy, repositioning electronics never exactly turned my key. Some of you sell amps. That is fine with me, but pure R & D has it's pleasures ... not that I really have any options So, first I have to vacuum up about three bags of dust, etc. It may be awhile, but, stubbing my toe on that big power transformer is a thrill in itself!

Please, "everybody does it" is no excuse. Any dictionary you wish to look in (provided it has been compiled by a true lexicographer/etymologyst, and not some smart-ass audio****** fool) will give you the correct pronunciation for this word: "AL (rhymes with 'gal') ni (as in 'nick') coh." Accent on the first syllable, short I, long O. Try it: AL-nick-oh. Alnico. See how it rolls off the tongue when pronounced correctly. This word was formed from the chemical symbols of the three metals which make up the alloy: ALuminum (or ALuminium, for you Limeys), NIckel, and CObalt. Note the word "nickel." If it is customary for you to say "NEE-cull" when pronouncing that word, then fine - you may say "al-KNEE-co." Otherwise, smarten up and say it correctly. And before any of you audio assholes take the Lord to task over this, just remember: next time you hear president Bush (or ex-president Carter, come to think of it, who ought to know better, having been a nuclear power engineer in the Navy) say "NUKE-you-lur," you'll have to keep your mouths shut. And you know you can't do that, so - AL-nick-oh. Don't even get the Lord started on "mic," which by any interpretation of the rules of pronunciation for English must be enunciated as "mick." The downright obstinate use of the ungainly and confusing shortened form of "microphone" leads to embarrasing constructions like "micing" (*must* rhyme with "icing," sorry, shut the **** up) instead of the instantly recognizable and pronounceable "miking." (Rhymes with "hiking" - see how that works?) "Miked." (Rhymes with "hiked.") And "mike" is the proper representation of the abbreviated form of "microphone." I want all of you to do something you've never done befo step away from your monitors and pick up a dictionary. Use a good one, a real one, not one of those "Audio Cyclopedia" bull**** rags. Look up "mic." Look up "miced." And "micing." Did you find 'em ok? No? Now, slowly, carefully...look up "mike." I ****ing told you so.

Why? 400 volts at 30mA is within ratings. Call it 25mA just to be comfortable. A supply voltage of 800 volts is about right. It's not a problem; really. Its within the Pda rating of 12 watts, sure, but since the screen is connected to the anode then the higher the Ea, the greater the grid bias must be to hold the Ia and one cannot keep increasing Ea and the bias indefinately. Sooner or later you get a point where the Eg1 doesn't hold down the Ia reliably, and for EL84 I would say Ea = 400V is about the limit. There are amps I have seen where Ea = 700V, but Eg2 was 350V, and a fixed voltage, and with RL = 14ka-a for a pair I measured 36 watts in mainly class B. Musical Reference did this. But you couldn't run EL84 in triode with Ea = Eg2 = 700V. If you did have 25mA and a 400V drop in an anode resistance then the R = 16k, but if the bias R at the 845 = say 33k, then load = about 11k. Using a choke plus the 16k is always doable and the dc load is thus very much higher so at 1kHz the load is mainly the bias R of 33k and the gain is maximum, distortion is minimum, and you get a wider voltage swing. But in an 845 amp there is no shortage of a high enough anode supply for the driver. Yeah, RC coupling is pretty easy. Indeed. Patrick Turner. Much thanks, as always, Chris Hornbeck |

FOR THIS PERFORMANCE TO HAVE A DEEP, LASTING EFFECT YOU SHOULD PLAY A RECORDING OF CAT STEVENS' "ANOTHER SATURDAY NIGHT" DURING YOUR VIEWING EXPERIENCE. THANK YOU FOR YOUR CONSIDERATION. STEP 1. OBTAIN A PIG. THIS ONE WILL DO: _____ ^..^ \9 (oo)_____/ WW WW Pig STEP 2. FIND A STURDY TOILET _ | | ___| | ( .' )__( Toilet STEP 3. SHOVE THE PIG INTO THE TOILET HEAD-FIRST. HE WILL NOT FIT. DO THE BEST YOU CAN. WE DO NOT HAVE A GRAPHIC FOR STEP THREE SO WE PRESENT A MOUSE INSTEAD: o..o (\/)S Mouse JUST IMAGINE THE PIG STUCK FACE-FIRST IN THE TOILET. THE MOUSE IS OF NO MATTER. STEP 4. **** THE PIG IN THE ASS. HIS SHARP TEETH, FIELD OF VISION AND ABILITY TO FIGHT BACK WILL BE RESTRAINED *AS LONG AS YOU HAVE STUFFED THE PIG PROPERLY INTO THE TOILET*. **** THAT PIG. YEAH, **** IT. JESUS CHRIST THE PIG DOESN'T LIKE THIS DEAL AT ALL AND THAT'S WHAT YOU GET OFF ON BABY. **** THAT LITTLE PIG. MMMMMM YEAH FINISHING MMMM PIG IN TOILET MMM STEP 5. EVENTUALLY THE PIG WILL DROWN, GET "****ED-OUT" AND COLLAPSE IN ON ITSELF OR OTHERWISE CEASE TO CONTINUE PERFORMING AS ****TOY. REPLACE WITH FRESH PIG. SEE STEP 1. |
