What a relief! No matter how many times it happens, at some point I always wind up adjusting my system to compensate for bad electricity! I know I keep saying it, and it is embarassing, but it's still true! I live near a school now ...

[quote user="Romy the Cat"] [/quote]I really do not know what is going on and how to explain the phenomena; I just dump it to you “as is”. Because of multiple reasons I decided to drain the Milq’s power supply when the amp shits down. I have a...

[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...

Hi all... yes, a clean power is paramount for a clean sound... I run my turntable and pre-amp on batteries and the difference in sound is amazing, while I never used outboard filtering on amps, BUT I have a public mains transformer at 10 meters from ...

Hi
I’m planning to build the Melquiades. Owning something that is better then a Lamm is definitely something for me.
Having 220V 50Hz. What changes are necessary in schematic?
Bigger PSU caps, inductors?...

Dear Romy, thank you so very much for mentioning our amplifier to your excellent forum. Indeed, during the last 5-6 years there are a lot of manufacturers “from non traditional hi-fi manufacturing countries”. In particular, in poor old Greece we ...

[quote user="Lx_"]The effects on sound can be described either globally or in details. Globally the music flows less, the sense of musical phrasing is diminished, sound tends to tighten, feel constricted, dynamics are also reduced. When trying to...

Romy,
I ran the tube conservatively at 40W, because it is still breaking in, and I do not want to push it too much power to damage it (then I will have to break-in a new tube all over again). This amp can give max power at 20.35W (12.76Vrms into 8 ...

Romy, in the contrary, it is very unfair to compare my 845 amp with the 6C33C. The main reason is the 845 amp used the best output/interstage transformer available, while the 6C33C's output xformer is pretty good but far from being best for the 6C33C...

I was slowing mingling the conversion of the power supplied of my second Super Milq from 3 channels into 6 channels and I ask myself: is anything in that amp is made in the way that would allow me to close it up and never review it. Sure if I move in...

[quote user="Romy the Cat"]3) There is a mistake in Milq circuit. The B+ of the driver stage has almost insufficient amount of critical inductance. It was because I drew the circuit having the Super Milq in my head where the PS was feeding 3 stages a...

I am finishing us to setup my listening room and I have my PP2000 blowing up sometimes (go to protection bypass mode) when I use powerful SS amp for ULF along with Melquiades and the rest of the systems driver from one single PP2000. So, I guess I wo...

I have written in past that for some mystery reasons my PP3000+, and I presume all other PP3000+, do adversely affected by switching power supplies in the feeding line. I have PP3000+ and older PP3000 and both of them works wonderfully, one on main l...

Hi Chris.
After much consideration I decided do not make one new toroidal “compromised” transformer that would be able to serve the needs of my solid-state rectification AND damping diodes at the same time. For solid-state I need 3A/220V but f...

My curiosity peaked with Jessie Dazzle’s last few posts. I realized that, in France, he receives 220v, 50 Hz power. I then recalled Romy’s post at http://www.goodsoundclub.com/Forums/ShowPost.aspx?postID=1177#1177. I was wondering i...

Wow! I did not realized that almost 4 months have passed since I wrote last.
Quite a few things have happened the last 4 months that I have played with the 6C33Camp/preamp combo. I have tried at least 3 different vendors on the Ulyanovsk type, the ...

It, looks like the problem with the steel chassis picking up stay magnetic fields from my Super Milq’s power supply is about to be gone. With the introduction of the 3 extra single-stage channels I needed more current for 6.3V filaments and slightly ...

I am bit confused with that new report. Under no circumstance I would defense Pure Power, nor anybody want my defense, but the reports I hear juts do not makes sense. If look like Pure Power grade for extra 30% or 50% power with new units, I do not r...

Jessie,
Actually the tendency of manufactures to isolate ground becomes almost common among any more or less serious manufactures nowadays. The main’s ground is so polluted in US hat it is scare… or even dungarees. I remember a few years ago when I...

Jim, I have sent you the tubes – it might be an interesting journey.
I send you:
1) 6C33C that was working with both cathodes approximately a year. It is not dead year but it is deep into retirement age. Run it at 220V and 200-250mA full-tube,...

[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...

I hope you understand that US
style socket means 220V, not only the sockets style. If it is
what you want to do then it should not be a problem, I am sure they use standard
