I got a .pdf file with April Stereophile where Art Dudley writes up about new Lamm 2.2 amp. I am long off the Lamm camp but I do observe what is going on with Lamm equipment as I feel I do have a good grip about it.
I have no idea why Art Dud...

[quote user="drdna"] It is NOT that better tubes have no vibration. Instead, the tubes that sound best to me seem to have a sort of springy sound, like the sound of a water drop or the sound of the tabla drum being struck. [/quote]
Interesting. My f...

[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...

[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...

Hi Romy,
I just want to add my experience I had last year with a transformer based (actually it was an autoformer based) "passive" preamp. I thought that this could be the final solution in my preamp quest. Alas, it was not the case.&nbs...

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 ...

I was yesterday drawing plans for the Zaratustra II’s chassis and was wondering how I might use it. The Zaratustra II turned out to be a little Monster, efforts-wise and expanses-wise. I hope it will demonstrate some results that will rectify the eff...

[quote user="Cosmos"] Anyway, as the description on our site on second paragraph says, the third 6C33 located at the back, is used as the pass element of the regulator (controlled by solid state circuitry) providing 220V with 100uV of random noise &a...

[quote user="dl"]
But I
am curious (wary) about what you mean by the “one-sided” results of using a DHT
for the upper midrange (if I misread you correctly). [/quote]
What I meant is that practically no one uses "a good DHT...

Well, as a prototype it might work but as the Milq sound
that I was implied the amp with no gas tubes in bias supply is not good in my
view. I never was satisfied the way how a regular 6E5P driver 6C33C. To me it
was very perfunctory and much unso...

[quote user="Paul S"]Now I am wondering: If we go to such trouble to have transformers wound for our particular applications, maybe we could just as well be winding our narrow band voice coils and welding them to our/their own output tubes.[/qu...

[quote user="jessie.dazzle"]7) Location of power amps : Yes, the power amps sit within the frame, on their own sliding support between the Upper-Bass and Upper-Mid horns. For the moment I am using a pair of ML2s from 60Hz and above. (below 60Hz I use...

Gregm,
I do not think that to be reasonable is a tall order, in fact I would insist that I nothing but reasonable.
Still, I feel that it is a huge distraction for people and a disappointment for me that others see juts an amplifier with a bi...

Jessie-There are the current japanese teflon sockets, and vintage american manufactured sockets - I think either should be fine. The pin springs on the OEM pair I replaced had no grip or spring characteristics. When the pin holders are bent, they ...

[quote user="guy sergeant"]What you say may be true. I'm not sure there was an amplifier available in the mid to late 1980's that would have been suitable for these. They did get good reviews but I suspect that some of this was due to awe inspired by...

Well, what is interesting in the subject: if the Cessaro guy will ever go for the DSET configuration in his commercial products? I am not certain but it is possible that in DSET configuration it might be possible to overcome the accused shortcomings ...

[quote user="KOTriode"] The Melquiades give me inspiration to build this 6C33C amplifier. It's on a stereo chassis that has few unique features - Vacuum tube rectifier separately for Input/Driver and Output tubes. - Regulator using the same tube ...

It is sucks to live with Russians Tubes. It is particular sucks to live with 6C33C. They are all deferent when they new, they age very ungracefully and differently.
The life with Super Melquiades, where I use 6x6C33C driving individual channe...

[quote user="Paul S"]Some time ago Romy threw me a fish in the form of two numbers, 280 and 185, meaning mV and V, respectivly, and I finally got around to chowing down. I was getting annoyed with the sound this morning to the extent that I bus...

It turned out that I made my Melquiadenisation with 6C33C. Not practically because it is good or bad tube. The choose of 6C33C was partially accidental: in the beginning I was trying to make an amp that would be able to work in multi-app configuratio...

Romy,
Sorry for taking so long to get back to you… (this being the summer time in a Latin country, I still have no internet connection at the new place).

I got surprising amount of emails form visitors of my site asking is I will be going to CES-2008. Nope, I am not. My days and interests with CES are over, I closed down that show and I hope the rest of the industry would follow me on it. In fact I ha...

After a month of listening exclusively Melquiades and decided yestoday re-switch everything and to play Lamm’s ML2.
I was quite shocked with the result and I did not anticipate the ML2 could be so way off. I will not elaborate about the a...

I think I need to make some commentary in here as BS will be swallowed as usually and somebody shall take stand on it. Before is a small prelude. Sometimes back in his comments about RMAF 2010 Show Report the Federated Mike wrote in his blog:

Well, I would say that “something is wrong” as what you report it is not how it shall be. I had my doubts about the rational to use 6C33C in direct heating coupling but the “danger” in direct coupling uselessly coming from the plate of the driver...
