I bet Taiwanese got tired of getting paid cents on dollar (and usually late) for product they developed and manufactured. The real guilty character in this all affair is Romy the Cat and his rumblings . Without it Pure Power would be selling as it wa...

He did note that the ML2.2 uses a different OPT, and also that it uses "less feedback" than the ML2.1 (which AD owned for several years). I wonder what this means, "less feedback"? Why would Lamm mess with that very effective scheme? Does he just ...

[quote user="Wojtek"]" The only concern being that ML2 is a feedback amp and Mel not. [/quote] And it is exactly why Lamm is able to drive more or less successfully those sub 90dB loads but Melquiades is not. The SETs with no-feedback are VERY sensit...

[quote user="jessie.dazzle"]A possibly dumb question here: When you and Paul give figures in milliamperes, where are you measuring the current (at what points), or are you extrapolating the figure? [/quote] The 6C33C current is measured in mA. The wa...

It might be not directly related to the subject of this thread but I do feel that it has quite a good relatively. Are you laughing that your Lamm made his new amplifier with a price tag of $126K? Well, think again. Do you remember as the ...

I have noticed the same kind of control and "density" of sound from KR audio amps, which are zero feedback. Have you tried this brand of amp? The one thing that I can tell conclusively about the two different amps is that neither one suff...

I have to say, I never gave it much thought, since, as you say, The Book says 5751s are an OK sub for 12AX7. I did realize that the gain was lower, but I obviously had a brain cramp in not interpolating the lower gain to "redistributed" global ...

Paul hear the Lamm amp's was one of my interests at CES. The only way to come to a verdict abought the ml3would have been If there were the possibility to switch from one amp to the other, and then compare. At lea...

I had two friends in NY City with Klangfilm Bionor who drove them with Lamm ML2.0. One of them had 405 footers and another had fool filed-coil version. I did not look into details and if I remember correctly the driver were in fabric cocoon but I do ...

N-set, at this point I am under impression (not conviction however) that a hybrid with some kind of harmonic correction circuit can do the job but spend much less blood. I have to admit that the best hybrids that I head had (Lamm M1.1) no where remot...

Paul,
The idea of the not threaded forum is good that it is always there is opportunity to go back to all there and update own views, or to extend them. In many moths/years when the ML2 stop be a novelty for you, you might return to this thered and ...

Paul, I do not remember I had problems with 6AK5 sockets, and frankly I feel that your preoccupation with small socks of ML2 is a bit strange. If you “keep getting noise from the 12AX7/sockets, and this noise gets resolved when you clean the connect...

I got new 6C33Cs for V2s from Lamm because no one else wants to match them, let alone match them for gain; but the loud thump through the speaker still happens just when one amp self-switches from warming its filaments to full-throttle oper...

[quote user="Paul S"] Any ideas for sources for 6AK5 and 5651A? Seems like most of the ML2 tubes are "hard to find" from local sources. [/quote]
I do not know why you say it. Both 6AK5 and 5651 are very common and very inexpensive tubes. The 6...
|
|
Well, I never seen it happens but who know – that might be if some use “violence” on tubes. The sad part is that to replace these sockets is difficult. I have replaced in ML2 the 6C33C sockets in ML2 - it was easy but the 5651 are PC board-mounted an...

…. what tube’s socket is arcing. If the tube juts started to ark then bending the tube legs, cleaning the sockets 9scabng the meta with no marks of the ark left) and treating it with conceive grease might help. Do not forget that most of the ...

Skushino, from what you say I presume you use two pair of ML2, right? Yes, what you say is correct but if I were you then I would not introduce an addition caps to signal path. In my view the best scenario for high path would be to minimize the coupl...

It is also possible that I'm reacting to a lack of true dedicated mid-bass. As previously mentioned, while the pair of 40Hz horns are under constructon, I co...

Somewhere in 1997-88 I bought a hundred 6C33C. I believe during those years the where more expensive then now and I paid around $7-8 per tube. Over the years burning the 6C33C in pair of VK-60 (8 tubes), two pair of Lamm ML2 (ML2), ML2 with Melquiade...

There is no meaningful mutual conductance or bias matching for 6C33Cs (in context of ML2) besides gain matching, ...

Tommy,
I would not characterize myself as “die hard” anyone and if I would then my selections in audio would hardly relate to my alleged “die hard” inclinations.
Lamm’s stuff is perfectly fine – as good as it could be, within the scope of Lamm’s o...

Rony,
After reading my post about the undersized core (for the given current) of Lundahl transformers you might be an impression that Lundahl are some kind of second choice. The undersized amorphous Lundahls forum is second chose for an ultimate ful...

[quote user="Paul S"] One ironic thing about the ML2s is the contrast between the fantastic workmanship and the mostly average parts. [/quote] Where did you see the “mostly average parts” in ML2, Paul, come on have some sanity and go over your craz...

[quote user="Wojtek"] Roman, could you (or enybody ) elaborate a little bit on JBL L8 and its application ? Not so much sensible info on the net besides that its a fullrange usefull in 40Hz-8kHz. [/quote]I do not know, how can I elaborate if I never ...

[quote user="Paul S"]If this is the case, then the Morons will effectively have less rather than more power unless they are more careful than usual to match the loads, which seems like the opposite of "what the Market demands". Cranking up the NOS 1...

Positive Feedback published David Robinson’s review of Lamm M1.2 amplifier.
http://www.positive-feedback.com/Issue34/lamm_1.2.htm
