BTW, Jessie, this morning I opened a Super Melquiades and made some changes in plate current measurements. While I did it I took a shot of the Super Melq inside. The former image was made juts when I finished the amp. The current shot is actual stage...

Sure, Chris, if I would be able to make the air-trans of acceptable size then I would defiantly go for it. If I pretend that the Super Milq pushed some boundaries (and I do feel it) then to use an air-core transformer for HF channel is exactly what i...

Somewhere within this thread (or perhaps somewhere else) I have mentioned that my own playback systems last times was dead-installed into the DpoLS approximately 5 years ago. I kind of did not make a whole a lot of attempts with DpoLS since I was doi...

[quote user="skushino"]Romy, please elaborate on your experience using a 2nd order crossover. What do you mean "rules of the game change completely?" Why did you try the 2nd order? Are you concerned with damage to the driv...

OK, got the Placette from the second round of "modification", it took 15 second to confirm that the HF problems that I sniffed out was not there anymore – so the absolute transparency is back to the business and this time the word “absolute” could be...

OK, I have conceptualized what I need for the tweeter amp. It will be MilqEZ – the same Milq one with 6C19P at output. I will use the Super Melquiades power supplies but the HF channels will host own last caps of the filters and own bias of the both ...

Hm, that is a good question. I honestly do not remember. The 6ch Super Melquiades has 7A fuse but I have no memory about the fuse I used in single channels amp. During the assembly I used the lamp fuse – that is given but in the final version I just ...

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...

[quote user="Romy the Cat"] In the 2008 I have a few immediate goals:
1) Finalize the 6-chennals version of Super Melquiades and integrate it with Macondo
2) Finalize the “End of Life" Phonostage:
3) ...

Hello, loudcloud,
The Milq’s meters are by Hoyt (link). You might look at
http://www.hoytmeter.com
and from theer your might customize it in any direction wish. They are not dirt-cheap but I fine them reasonable for what they do. Here is the pict...

Believe me or not but since last spring when I undertook the single-amp conversion and went for the six-channel Super Melquiades my playback never sounded as I would like it to. It was better or worst but it was never how I meant. The last week the t...

Well, it is getting interesting. I was able to make my Hillock TV-2 tester to test the 6C33C. I spend a few hours to filtering the plate voltage and replacing a couple resistors to 50W instead of the 5W. The plate coils in TV-2 is 100mA but it looks ...

I do not know why people go into low-sensitive loudspeaker and they go crazy in order push the last drop out of the class A2 operation. From a different perspective the Macondo’s woofer towers with 97.5dB sensitivity are low low-sensitive loudspeaker...

Sine my call for somebody builds for me a full range Melq was not answered:
http://www.goodsoundclub.com/TreeItem.aspx?postID=2492#2492
I decided to put it together myself. Now I understand that letting the first amp to go was a mistake....

Since I got my stable and good quality electricity back I recalibrated my bass horn. Again, I set it up with very precisely and absolutely without any measurements, juts by ear, to sound exactly how I want it to sound. This is in a way my crown jewel...

I put the Super Milq and the new one-stage Milq today and was playing them together in order to see which would be more interesting. It is imposable to “compare” as is the upper bass and lover mid channels as the Super Milq has all kind of line...

Those damn Russkies always threw surprises. Using in Melq the Russian-made tubes, probably very few the most remarkable tubes they ever made, the life defiantly threw some hi-fi astonishments.
The people who follow my saga with Melq know that I do n...

Ok, the 6-channels super Melquiades is done, closed up and I made a few pictures of the beast. I have to admit that I do like how it amps turn out to be packaging-wise: the layout turned out to be very good for 3 channels as well and for 6-chennals. ...

I was listening toady Rossini’s “Sonata per Archi” and suddenly a strange feeling stroke me: I become suddenly queries about “more power”. It was not that something directly encouraged me in the Sound that I am getting in here. I never heard th...

[quote user="Antonio J."] The builder regards VR1 more like an "offset to 0" adjuster than a bias control for the 6E5P since its working range is quite narrow. He asked me to know from you if along the 6E5P's lifespan it needs further adjustment...

From the point of view of a methodological purity indeed the location of a vacuum
tube amplifier atop of midbass section does not make any sense. B...

[quote user="rdrysdale"]So how do you suppose the proper DPoLS can be located? With a system like Steve Schell and I are working with, everything weighs hundreds of pounds and to properly evaluate changes would take days, maybe even weeks f...

Yes, Jim, you put it very well. Still in case of the 6C33C it only possible to cool the glass and I made experiments blowing a strong flow to the glass and it did cool down the plates. The problem is that it is not a good idea to apply a strong flow ...

Actually I did have it is past. At that time I used a low-pass filer on my upperbass horn. It was 103dB sensitive driver of 16Ohm, highly inductive, and I needed somewhere hear 800Hz, speaker level, the first order. Being an extremist I got 3mH coil ...

Romy,
Thanks for the updated image of the Super Melquiades.
For the past 10 days I have had to temporarily stop production of the horns and put off researching components for the amps; all this is due to my moving to a new apartment sooner than...

You are correct about the load matching, for the Super Mild LF channel a half-Ohm of loading change bass quite dramatically. Still, the idea was to make this SET completely without any intentionally implemented feedback. It is juts not necessar...

[quote user="cv"]I wonder if it is the reactive components (blocking caps etc) that are to blame here, seeing as much of the problem is in the lower bass.[/quote]Chris, what you said made me to think.
Look, the output of Bidat and a SS buffer that b...

[quote user="jessie.dazzle"] I bought the ML2s to use as a development/reference tool while constructing this horn system. The idea being that I would first use them to dial in the horns, and later as a reference, to which I would compare and evolve ...

Well, I spent today a number of hours trying to advance my observations regarding abilities of the one-stage Melquiades. It was quite interesting. Thankfully the electivity today was way better during the second part of day. I loaded the 6E6P heavier...
