Well, David Berning is about as clever as they come, Merlin, that's for sure, and you don't hear David making a lot of claims for his gear. That whole step-up, HF PS/carrier idea is pretty cool, all right; I think Carver did one, too, year...

Hi Romy,I am very interested in what you have found out about the 6C33C tube lifetime because I am using a pair of Silvaweld OTL tube reference (their name for them not mine) amps that use 4 x 6C33C-b tubes per monoblock (so a total of 8). Thes...

[quote user="Romy the Cat"] Good question, HookEm. I would say my answer would be 2, “Any single driver back-loaded loudspeaker in general”. Do not get me wrong, driving your, or any other single drivers would do fine by ML2.0 and you will be able to...
|
|
[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...

Merlin here is the Stereophile measurements on the Lamm ML2.1http://stereophile.com/tubepoweramps/1004lamm/index4.htmlAs you can see the rise in distortion vs. frequency shows only a small rise in distortion even down to 10Hz. This is an indica...

Personally I am not interested to talk about reviewers, because it is wasted time (they don't review something, they design a Product Placement and maybe they add that they 'like' it...)But, I really would like to know what situation they describe as...

[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...

I went recently at the Soundstage.com site and read Marc Mickelson’s comments about ML3.
Marc Mickelson had an “honor” to make my site in past:

Positive Feedback published David Robinson’s review of Lamm M1.2 amplifier.
http://www.positive-feedback.com/Issue34/lamm_1.2.htm
Frankly speaking I do have interest to see what people might say about Lamm M1.2. Not that I care about a review’s ob...

[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="George"] Even though a PS Audio and others create a perfect AC sine wave this does not seem to be the answer, even for low draw front end components. It seems that some type of problem is still coming through. [/quote]
George, you not n...

[quote user="Paul S"]"...Obviously I will have to keep a closer watch on the OPs..."[/quote] Paul,Though I don't let my ML2s go more than a month without verifying the bias, once, due possibly to a screwy tube, one ...

I regularly visit 6moons News Section that lately became quite good sources for audio news. It is same that Srajan not willing to share the news in RSS or compatible format, anyhow…
The today new is Elina Lamm announces that "we are extremely please...

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...

[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...

Lots of good information in there, if one has some idea of what it means in terms of sound and how it might be integrated into a system. However, some of the guys who are the smartest with respect to circuit design seem to have n...

Jessie, I think you go overly crazzy in here. The buzzing you got is from your inaccuracy of your “small clips”. A Regular divider at input should not have ant noise, regardless the resistors were used. Do not spend a lot and do not go into the craz...

Adrian, I wonder how you wound up with the never-mentioned FET 10? FWIW, it was one of the better all around phono stages I've heard, and - not that it matters - I prefer it to the EAR 834 I heard. Is this another case wher...

Honestly, we're gonna have to start calling you Romy "magnetar" Bessnow if you keep changing your mind like this...*My S2s all seem to measure completely differently, will have to get some more accurate and careful measurements done I think with...

Romy, it sure sounds like you were right when you said that at any given point the ML2 was a work in progress.The .033 uF 950s in my amps are indeed 1000V; maybe L got a quantity discount; maybe they're 2nds; who knows at this point why the...

Your points about "better" versus "correct" and "tactics" versus "strategy" are well taken. You are pretty good at saying things I have thought about for some time but never articulated, perhaps because there was no one to tell. I ha...

As I process what you have said about "blending integrity" I hear a trumpet blowing right at my face, just like I did last night. But obviously this is my imagination at work. Do you mean in general the way tones exist and integrate ...

What speakers are your using? The “4R at about 80 Hz before going back up their average 8 Ohms at 30 Hz” is not good for SETs. I prefer to have 16R and do not let it to drop below 12R. Lamm is quite fixable with loading, probably because ...

dI, thanks for your post. It is an interesting post, might I
comment upon it? I do not share your experience with Melquides amplifier even those
I know exactly what your were taking about when you wrote about changing own expectations

It is difficult to generalize but I will. As much as ribbons with each hertz down sound more and more unpleasant the low power SET amps with each hertz down in bass region more and more and more loosing ground. Ok, I am not taking about the real bass...

Hato,Its very simple, and can be done without opening the amps.If you receive the manuals with the amps, you will find that they include clear instructions for voltage selection.If not, do as follows:There is a voltage selector built into the IEC soc...

Here is another advantage of multisampling and DSET in particularly. There are many moments in amp that in one or another degree affects transients.The capacitive coupling for instance works fine but as long the amp sits in class A1. As soon amp hit ...

Regardless of whether or not I understand you and your Milquiades, I do understand for the first time in 40 years the value of a real change in my audio perspective, which the ML2 immediately provided for me. This is not to say that I have alre...

That's one big tweeter, Romy, and, typically, it was made that big only because they intended for it to go low. I keep wondering about the effects of the extra mass, if nothing else, but also about dispersion and window blind effects ...
