[quote user="guy sergeant"] I have not drawn any conclusions about how this amplifier might sound. I cannot imagine how the input stage you use will behave and how that will impact on what the 6C33 does. As I've said previously the Lamm amplifiers us...

[quote user="behhl"]Hi Romy, but I am simply curious that your Designed-&-Made-Yourself have always had the flavour of the names and places from A Hundred Years of Solitude ... Macondo the village, Melquiades the gypsy ... so why the departue now...

I have posted about some of my recent experience with longer "naked" HF ribbons in Romy's "Water Drop" thread. Here are some observations that relate these drivers back to the ML2s, along with some other recent ML2 trivia.My speakers are listed...

I certainly hope more people will get going on the different versions of the Melquiades amps so I can learn more about them. So far, this site is a crash course! I just hope everyone is paying attention when thye read here, over and over,...

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...

Today I had a chance to connect everything back together - I had been using a spare amp while the ML2 was out of service. After replacing the tube sockets, the problem amp's behavior is stable. Not sure if the cause of the problem was the loose pin...

[quote user="darkmoebius"] I would never just jump in and attempt to build the Melq (or any other amp) without months of studying the design … [/quote]
Good motivations. To simplify everything: the Melquiades was at attempt to make two stages, capac...

Or: Buy a new hammer and - for a while, anyway - everywhere you look, there's something that calls for a hammer.The electricity today was shite (thanks, Smart Grid!), but I none the less enjoyed some of the music I played. While playing Brahms' PC2...

user="Mike"] Originally the speakers were to be the
Verity Audio – Montsalvat speakers.…The Monsalvat require 3 pairs of
amps. So Lamm sent ahead 3 pairs of ML2.2 amps to CES. [/quote]
Ok, Mike. From DSET
perspective it is a fooli...

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...

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...

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...

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...

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 ...
|

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...
|
|
OK, I'll go first, then. Congratulations on actually letting go, Romy. I'm still not exactly sure why you feel the need to make such abrupt, extensive changes, but I mean I'm not sure I understand everything you have just said about it, vs. not under...
|
|
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...
|
|
Glad to hear you've found a short cut. Of course you don't want to run the Auras too high, but the IB should allow them go go higher than they might in a box, and it should also improve the transition to the bass. If you decide to go SET it might b...

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...
|

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...

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...
|
|
One ironic thing about the ML2s is the contrast between the fantastic workmanship and the mostly average parts. Of course, the sockets are plain crappy, and I suffered plenty with them until I started using the dielectric grease. I have been too ...

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...

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...

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 ...

What problems with the Johnson sockets are these trying to solve, again? Would they really be better overall than a lower mass design along with chassis through-holes, like the ML2, etc.? If a reader is using these, do they appear to better stabiliz...

[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...

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 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...
