    What constitutes a personal attack can depend largely on one's personal point of view. This reminds me of several scenes in the Godfather trilogy, where they machine gun or garrotte somebody, and then always say “It's just business. Nothing personal.'' For the guy who gets whacked, however much he deserved it, it's very personal. So, maybe the original post amounts to a personal attack, even if the intent was, as I'm sure, to inform and alert members about a longstanding situation that not everybody here now knows about. But maybe a bit of personal attack was just what was called for in this situation. Nobody made the guy do shoddy work, buy cheap parts, try to profit off the innovation of others, not correct failures... Decorum becomes excessive when it suppresses historical reality. RobertR

    SOLD: Carver Fest Speakers with stands

    Yeah, Trav - the directions I wrote were useless for those plugs, as the writing was done before I ever saw the plugs. The key solution was to use the smaller alternate plug, the one that was included but not already in place. Even that one was a damn tight fit, but once done they worked very well. They proved how well when they managed to conduct enough wattage to melt the drivers in the famous suicide test at Cabin 7... RR

    When shown the M-1.0t MkII, Bob was only interested in the details of the mod - what was done, how much power was gained, how reliable it had proved to be, etc. He had nothing negative to say about it, and not the slightest thought of infringement. And Bob is a guy who has suffered a lot of infringement, and sued a few people about it. RR

    Interested, if I can scrape up the dough by Fest time. You didn't happen to save the little xlr plugs, did you? RobertR

    Looks like a lot of fun, but what the WAF factor?

    Genuine Snake oil - only $299/1.5ml!!

    My favorite way to do fuses is to solder in a 'pigtail' type. Not convenient to change, and they cost more, but no question about contact. And in normal use I don't think I've blown more than a couple of fuses in almost 60 years. Well, except when working on something that's already ailing - then I solder in a little fuseholder and use the everyday fuses, until the danger is past. RR

    Dielectric grease is engineered to be non-conductive. Non-equivalent analogy. There is no point to such arguments as this, except to remind people that not everybody agrees with all the hyped snake oil; some of us are from Missouri, and don't want to see such claims accepted as fact until there is some tangible proof, not just anticipation bias-based claims.

    Regarding the Green Ink Farce: Don't forget, there was (as always) a pseudo-scientific explanation given for why it was needed, and how it 'worked'. It seems that there is a lot of stray red laser light kicking around in a CD player, causing problems with the pickup; you know - interference, or whatever. So the green ink, being the complimentary color, will absorb all that nasty old red - problem solved! Then, as the hoax developed, it became mandatory to buy just special (and more expensive) green pens - the ones in which the color was specifically engineered to be precisely the right frequency to gobble up all those red culprits. If people still use these pens, it's no great surprise - humans don't change much. I read about biased listening all the time, right here. Somebody is doing an 'upgrade', and before they even get the material delivered, they are talking about how much better it will sound. Then the job is done, and guess what? It sounds just like they 'knew' it would; that new line cord was just the tweak the ol' amp needed! Test equipment can show changes that your ears will never reliably detect, e.g. in frequency response. But of course one of the favorite promises is a better "sound-field". Or the stuff about warmups, break-in periods, etc. - all things not really measurable. I never pay much attention to any claims that are based in biased listening. If listeners first claim to hear something, but then can't distinguish it A-B-X, It's - Just - Not - There. RR

    I would hardly classify this as Way Offscale. It is central, pivotal, seminal to understanding a basic human flaw, and how it affects this entire hobby. As I have written lately, and not so lately - Anticipation Bias is extremely powerful, and present in all of us. This is just another example of the results of letting it go wild. Audiophiles, or the Golden Ear crowd, or whatever you choose to call them, don't have any better hearing than anybody. They just have far more creative imaginations. RobertR

    Audio Cheapskates

    Those cabinets were from the factory, and not uncommon. Remember, that model was the best selling Phase Linear model ever. The drawback with the PL1000 wasn't looks, it was that it had unusual dimensions, and thus didn't stack well with all the usual 19" stuff. The wooden case just makes that problem a bit worse.

    So I Guess Knives Are Next ?

    "Carversite is dedicated to Bob Carver and his many audio contributions" Really? Then why is this thread not removed? What has changed here? Is this now a place for the repetition of endless arguments about political wedge issues, things that have precisely nothing to do with audio? If I want those arguments, they are not hard to find elsewhere. And if I want to see how safe 300 million guns are making America, I can look at the day's headlines, anytime. RobertR
  12. Barryg - The kit amps will be different physically, for sure. There is to be a pcb, for one thing - Bob is just getting started on the mechanical engineering at this point; he has a ME helping him with that. As to circuit differences, knowing Bob there will have been at least some minor changes; with him, change is ongoing, perpetual. RR
  13. When Bob first talked to me about this amp he said it put out about 35 watts with 6L6's, and twice that with KT-88's. And with KT-120's around 105w. After he got around to trying it with the 150's he said those added some more power, though not really enough to bother about, especially considering the price of those tubes. But anybody can try them if they like; Bob would probably order them for those willing to spend the difference, and his cost for tubes is a good deal lower than for most of us. Bob is an engineer. Remember what engineering involves – creating something that's the best that can be built AT A PRICE. Consider the absurdity of a push gasoline lawnmower with dual 4-barrel carbs. An engineer's nightmare - total waste. And it would be poor engineering if Bob's chosen transformers, for example, were so oversized that they could support another pair or two of output tubes. Ideally every component reaches it's limit at about the same power level – that's good engineering. RobertR
  14. Right - the noise machine! It's an idea I've had for several decades. When CDs hit the market, there was always the complaint from the anti-digital faction that "something is missing" in digital recordings. Right - tape hiss! They were so used to it that they associated it with ambiance and high frequencies. And analogue masters were considered to be superior to the new digital ones, of course, for the same reason. Now, who will market a sophisticated, costly surface noise and rumble generator for the LP lovers? RobertR
  15. No, Z, it's the same document. You have to look very carefully for the subtle details. The schematic is for the 760, but shows asterisks on the extra output transistors, and associated resistors, plus a full-length heat sink, all of which are omitted on the 500/753 models. So same boards, but those in the less powerful versions are not fully populated. The 753 is nearly identical to the 500, but of course has one more amp channel board, and all that goes with that: another meter, another set of parts on the mother board in front where the amp boards plug in. I suspect also a different power transformer, capable of higher wattage. And for the 760, I'd guess higher voltage secondaries, as well. I haven't looked at it for a while, but I think if you check the parts lists you will find a few references to the 753, where there are differences. Maybe a 753 face-plate with three meter holes, etc. The manual issue was a pretty sloppy rush job, it seems, done on the cheap. Probably relates to the fact that the company was on it's way to going belly-up. Sad, because these are really good amps. Wish somebody knew what the bias setting specs were... RR
