[quote user="Chirag"] It seems the 6e5p is driving the transformer directly. I've used various versions of even simple mosfet followers to good effect at the headphone level, but never considered using a speaker level transformer. Did you and D...

[quote user="drdna"]This is sort of a sideways answer to this question, but having used power supplies with vacuum and soild state rectification, I also played with Allen Wright's SuperReg circuit and I really liked the way it sounded. A more stable ...

I have to admit that I personally care less about powerful full-range SET amplifiers. I do not take their sound seriously, in fact I do not believe they are cable to do “right full-range sound” and what I see then I always imagine them with huge, bar...

That was very interesting post, here are some thoughts of my about it.
[quote user="KOTriode"]Romy, No, the DAC was not set at maximum level (for best sound) while Cyrille listening to the system. It was set at normal volume for the whole sys...

[quote user="Paul S"]I got new 6C33Cs for V2s from Lamm because no one else wants to match them, let alone match them for gain…[/quote]
There is no meaningful mutual conductance or bias matching for 6C33Cs (in context of ML2) besides gain matching, ...

I spent a bigger part of day today to finish the “End of Life" Phonostage, there were many things to do but it is now over. Done! Complete! Amen! I it closed up and sat in it’s permanent place.
A few observations looking back. First, I spent a LOT...

Well, I screw-in today the S2 with filed-coil into my horn. I decided to drive it with 2.4A. I used a regulated DC PS and did not employ my prepared for this tusk 4.2 Farad capacitor: the voltage is too high for my cap. The current gave me a ni...

Despite the tremendous popularity of the single-ended amplifiers have a certain group of audio people, let to be honest: the SETs do not sound REAL in audio people’s listening rooms. I was in many of those listening rooms and have heard many best SET...

Yes, it would be very interesting to hear the difference between a 6C33C amp with and without tube regulation, but also they are too many thing to try too, ... the possibility is endless here.My recent experience with two different ...

After a few years I have again pair of Lamm ML2 in my room and I decide to take advantage and render my experience with this amp into a format of my today’s understanding. I know ML2 quiet we and used it with a number of loads. Over the time I develo...

A few days back an audio guy from Mexico-city visited me from. We did listen some music, talk a bit about audio. As usually I interrogated him about the problem he hears in my sound. The people who were in my room know that I do it with absolutel...

Just finished one mono block 6C33C SE amp.To keep things simple (power supply only need 220V), I used a single driver tube (the second tube is there for backup if not going as planned) through an interstage transformer...

Anthony,
First of all, I would like to congratulate you on making your amplifier. I have been following your build from the beginning and now that I am building my own amp, I appreciate your work even more. I admire your plan a...

…and since it is in LL line I presume that it might be right along with LL2 Preamp – not particularly interesting preamp. In other words it is most likely the “positively expected” and “might be interesting” continuation of the L1 and L2 line.

[quote user="peter foster"] By "dynamic viscosity" do you mean the reluctance of an amplifier to be dynamic, i.e., the degree to which an amplifier sounds like it is bogged down, usually as a result of a poor rise time on transients, i.e., poor HF re...

Sine I informed public about Melquiades amplifiers I receive many emails from people asking me about the operation points of 6C33C. For whatever reasons people mistakably took me for some kind of 6C33C guru, which is am not. Moreover I could be hardl...

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...

A quick look at the Dally Audiophile web site suggest that anybody
mention the new Tidal’s Music Streaming Service. That is a new 16/44.1 Streaming
Service that the call "High Fidelity streaming service" by

[quote user="KOTriode"] Thank you for the comment on this amp, this is my first time of using the 6C33C tube, I decided to build this amp after reading about the Melquiades, this amp is just a quick experiment on the 6C33C sound, since I have a s...

It is sad that no one talks about it and it is very not clear what is going on. It looks like the companies that sell hi-res files feel that the phrase hi-res is automatically an assurance of some kind of “quietly”. Well, they most likely deal w...

[quote user="Romy the Cat"] Well, I have to admit that I did not listen the whole sound of AC vs. DC filaments yet. I will bring home today my DC lab supply that I use for my electromagnet coil and will give the try. I still at this point am not...

Dear Romy,
I have been reading the threads on GoodSoundClub about your journey with development of the Melquiades and Super Melquiades amplifiers. They are very interesting to me. I am pleased that your purpose was to produce a particula...

[quote user="Romy the Cat"]This morning I was listening Messiaen’s Tarantella-Symphony powering system from the bare AC lines. It was far from the sound I would like to have and I decided one more time to insult myself with PP2000. This time I decide...

Last night a friend of my visited me and we spend an evening listing Wagner. He played Wagner himself a lot and he begin to make comments about sound of different sections and instilments in my room. I stopped him as Macondo in the new is no wher...

A site visitor pointed me out the I never made an intended write up about the David Haigner horns. I just forgot about them… OK, let analyze David’s claims and his Alphahorn design. I would say right the way that I do not like the Alphahorn’s id...

Was talking with various audio people about the 6C33C I was amazed that people are so clueless about this tube. The people are so filled with some foolish prejudges and faulty notions about 6C33C that I deseeded to put together a brief “6C33C user ma...

The very much non-definitive EAR 834P Modification Guide by Loesch Thorsten
Hi,Given that Romy already let the proverbial Cat out of the Bag (pun intended) I think I may have to make good here....

It looks like the Europeans have for themselves some kind of audio festival on regular base.
