This is kind if funny as I never thought that I will go this way. I kind of have a need for an amplifier. For a normal full range amplifiers that would be able to drive conventional speakers. I really can’t use the Super Melquiades as it has the live...

Jim, I did try the anti-phase transformer in the secondary but I felt that it did something to sound. I can not do it on primary as I have the pate coil for the first stage sitting on the same transformer. Regarding the sweet spot of the 6C33C - I ha...

Eventually the right channel of the last revision of the 6-Channel Super Melquiades is complete. It has the new dedicated power supplies for single-stage amplifiers, the 600V Schottky rectification for 200V line and 1200V Schottky for 400V lines, the...

[quote user="Romy the Cat"]Last night I was listening Zubin Mehta’s recording of Bruckner’s Symphony No.9. It was his first recoding from 1966 with Vienna. I am not a big fun of this performance all together but it has spectacular first movement...

I am taking about coupling capacitor between driver tube and the DHT. There are zillion way to do it and no one said that they need to be used. No one proved yet that a very good quality of caps shell be worse than other methods. In my case since the...

I have to admit that although the Macondo “Water Drop Tweeter” sounds very good but I do not have that “shocking sound” that I got from the “Water Drop” during my initial introduction to it. I kind of always felt it and I thought that I get use t...

MochaMike, yes you are correct it would not be the “softness” but rather”liquidity”. Still what you are taking is applicable for the paper cone 4 to 15" drivers not compression drivers. Who knows how the compression drivers will react.
To the rest ...

[quote user="Romy the Cat"]Anthony, I do not know what you new buffer is. A few notes. The difference between sub 10R and 300R of output impedance is significant for the load you have (Milq) between your new buffer and your 10Y preamp. The type of th...

[quote user="Romy the Cat"] Make an experiment, and I will simplify the case quite assertively. Take a typical compression driver, cross it at 800Hz, second order and load it into a proper contemporary horn (Tratrix or JMLC) of 300Hz. Listen that hor...

For a casual observer it might appear that I am constantly fought with my ULF, finding and loosing better and worse configurations. It might be so but I have a very strong sense of objective of what I would like to accomplish. I want to reinstat...

Continuing in my quest to the finding the new DPoLS with my Super Milq I did some “critical test listing” today. I’m certainly getting closer. I spent a few hours to play with the playback and I recognize that the first signs of the approximation of ...

[quote user="Romy the Cat"]However,
if I did it again then I would not do it in context of multi-channel amplifier
but rather I would make a maket amplifier able would test my ideas with it. [/quote]While I do like the idea of experimenting with MF...

Well, Jim, it is time to say “Oops!” I told to myself do not make any posts early morning unit I eat a bagel but this mooring I disobeyed the rule. Anyhow, I do not know how I come up with 28.5V RMS. Defiantly it was peak-to-peak on the scope and I r...

I would like to share my observations about public perception of Melquiades - The Realty Reconstructions Amplifier.
Melquiades, or as I affectedly-abridgedly call it “the Melq” was released to pubic exactly a year ago:

After 4 days of suiting in boxes in my listening room today is my day off and I decided to dedicate it to play with the new Pure Power 3000+.
I desired to use just records and connected all amps, preamps and phonostage to ol...

Ok, it is a lot of information on my plate and I am trying to make sense of it. Below I will share my observations about the new Pure Power 3000+.
The first thing first. In the post I made a few days back:

[quote user="Romy the Cat"] The idea was very simple: to convert the C filter into RC filter, to employ the Silicon Carbide Schottky rectification diodes that showed themselves so nice in 6-ch Melquiades and to beef up the preamp with large bet...

[quote user="ml8"] If you think gas regulators make sound of 6E5P so nice, didn't you try putting gas regulator tube in the grid of the 6C33C, and why? [/quote]
Sure, I trued. It sounded very bad. I pull out of my butt any imaginable rational with e...

[quote user="Paul S"]So this amp would not have to deal with a crossover? One R and one L in the signal path, it looks like a headphone amp, maybe a dream circuit for a light piston, HF only, given no cap/coil load at the [ribbon] driver. [/quo...

[quote user="AnonymousUser"]hi-i have downloaded the circuit diagram for your amp but wondered if you have any photos of the "guts" so i can see how you laid yours out ? [/quote]
I do not have a full rage Milq anymore. I have only the 3-chanals Supe...

I am very much do not like the current state of my mind about the single-stage Milq. Let me to explain….
In 2001-2002 I spend some time trying to assess the sonic influence of PS to sound. After making numerous tests and prototypes I concluded that ...

Contemplating now how to organize biasing for 3 singe stages of my 6-chanls amp I was faced the dilemma: do I need to bias my tubes. The 6E5P/6E6P are Russian tubes and it means that are very different right from the boxes. The Milq, driver tubes, be...

Iraschwips, I do not think that it has anything
to do with impedance at all. You might have sub 1R impedance of your
loudspeakers and perfectly compensate it by wiring a custom transformer that
will perfectly work against lower impedances. I would...

I am looking at my posts at the forum and am trying to
figure out when the 6-ch Milq as made. I think it was during the late 2007 beginning
of 2008. Well, the Super
Melquiades then is 10-year-old then….
One
way or another I got my first screw ...

[quote user="Romy the Cat"]I was thinking about this: how come that driving 6C33C (in fact driving anything one can imagine) the 6E5P was very fine but driving 2A3 it was dull like hell. I opened the amp and tested all – everything was perfect but th...
