I see, I never thought about it... If you are correct then I will not be able to say, “how it works out”. I would definably be able to say “how it sounds” in regards of a speaker-level 3uf of “Vitamin Q” vs. 30pf at line level, but I will not be able...

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 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...

Paul, harmonic balance and frequency response are different things. We presume that if s playback has right (acoustic-like) harmonic balance them, only then, we can talk a bout sane frequency response. Do an experiment. Take your ML2 and load your sp...

Wojtek, in reality all “problems” that you picked from Paul’s comments are purely inventions of his mind. ML2 is truly “turn and forget” type of amp and it requires no dancing or prying around it. The 6C33C requires some attention when it is new but ...

[quote user="Paul S"] I have stated several times that the ML2s are less sensitive to bad electricity than my phono stage, and this is true. However, this is not to say that the amps are immune to bad electricity. In fact, it is the effects of bad el...

Reading you guys I can hardly imagine how you can use this amp at all going trough the hassle with the tubes and bias.This amp needs to be monitored and pampered constantly and getting tha thing to work seems to be ceremony on it's own . How do...

if there was any taker not even mention for oportunity to get ML2 . It's not going to happen in this life though ;)I'm pretty sure that in writing the whole setup/tube procedure seems more tedious than in actual use. Sorry , I didn't want to be a pes...

I could not say if/how very high speaker efficiency and/or FR limiting might effect the issue of a sort of "shuffling" of pitch/tone/harmonics as SPL and complexity shoot up and down, ie, tonal integrity versus dynamics. No amp in my experience...

Wonder if ordinary "di-electric grease" would work on tube pins? Anyone ever try it?It works for old car distributors and electrical service connections, which is to say, other high votage applications.Like I said in the ML2 thread a few p...

If you have nothing more than low hiss, as you describe, then you are probably about There. In my experience, at any rate, it's either some hiss or some hum, compared to true silence, like the ML2, etc.Do not give up before you try all parts hard wi...

The recent protracted electricity nonsense has given me some particular situations to think about, and the Shannon references have started me thinking about the "Point of Divergence", not just in terms of sound and music but also in terms of con...

Hm, it was 3 days as I did not play my playback and keep my Milqs off. I tuned it on today and… it was the most horrible sound that I heard from those amps. It took 6 hours for them to continue run in order to sound more or less acceptable. I remembe...

I've been keeping this ML2 log for myself, of course, but also for anyone else who wants to chime in. It has been my intention (and practice, I think) to report not just "sucesses" but also whatever happens, +/- as it happens, with no rega...

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 ...

|
I have to admit that the live Zander’s Bruckner Fifth from the end of 2007 made me to re-think how I would like Macondo to sound. It is not that I recognized new Macondo’s “Hi-Fi problems”, whatever it has I am very comfortable with it, but I rather ...

A few days back I posted the following post:

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...

[quote user="Paul S"]Lamm did choose to use some of the driving ideas from his proven SET amp…[/quote]Yes and no. ML3 design wise, as I understand is, in fact is not as interesting amp and it might be otherwise. Vladimir went for the target marke...

[quote user="HookEm"] Actually, I would prefer moving towards a more permanent solution (for practical, and frankly, economic reasons); and if that means moving away from the single driver (yellow cone), so be it... Now if having the subs in place wo...

[quote user="AlexBerger"]I tried Amperex ECC83 "Bugle Boy". They sounded bad in the EAR RIAA. I like more modern Amperex ECC83, Holland made with orange-red prints.[/quote]Yes, the Amperex "Bugle Boy" are horrible tubes. They have huge publicity amon...

[quote user="KOTriode"]Romy,The normal bias for the Golden Grid tube for 200V Plate at 200ma is about 70V-80V for the good tubes, the bad tube read 0ma at this bias, when drop to -30V it start reading some current, but can't get to 150-200ma current ...

[quote user="jessie.dazzle"]Yes, in a way you are correct; the wire is white but over time became sort of brown toward the socket; this is either from the metal contacts of the socket having oxidized in close proximity to the insulation, or simply fr...

After swapping all the tubes between the left and right amps, the cycling bias current issue (mentioned here in a previous post) seems to have settled.I now have another question, which I hope other ML2 users might answer; first the context: These am...

[quote user="jessie.dazzle"] Make sure the power switch is off, and connect the power cord.[/quote] Unless you are a republican. If you are then you need to change voltage with power switch on and power cord attached.

If Lamm had actually used the larger 950s in my unit I would probably be less curious about it, but for mine he used 10uF 935 couplers with small 950s for bypass (... I assume they are bypass caps...). Hard to imagine 10 uF couplers would not have a ...

[quote user="Paul S"]I also wonder about the supposedly simple but ever mysterious procedure for matching 6C33Cs for gain. Presently, my amps are ~ 2 dB apart.[/quote]To do gain matching we need a way to measure gain. To be precise, we need to measu...

LaurentAlthough I have whined that the ML2 requires "tweaking" to get its best, the truth is that it is closer to the dream of acceptable "plug and play" performance than any amp I have ever used. Which is a long preamble to saying I am hardly an ex...
