Finally done! A journey that took a total of 11 years after coming across this forum and seeing the Melquiades posts and schematic. Koshka has a beautiful body and will live on in my SET implementation of a 4 box solution. Here is the left channel po...

There is not permission required. You might repeat the original Melquiades if you wish. All that you need is the circuit and ~$1500 per monoblock. Currently I withhold the devaluing the Melquiades schematic as I need to accumulate my own live-supply ...

Yup i think i will use ac for filament,in my mind i wan't to copy and build the structure of melquiades ,so i don't need to recalculate anythink,only follow the stream, but maybe if i use 6,3v filament(i see melquiades use 12,6v) i must change someth...

I will say that I agree with what you have said, Roman; that DIY'ers most likely to build the amp are probably a bit anti-Romy. Too bad, I always say liten first and then comment. Too many people in audio get wrapped up in the theory and ...
|
Ever since the Melquiades schematic was published, I have been planning to build one, because the objectives and topology seem like they would work for my system. Unfortunately I am very much not a DIY person. Even though I have built my ...

I do not exactly comfortable with oxric’s preoccupation with “parts”. Yes, there are some amps that invest a lot of attention into parts quality – the silver winding in Kondo, oil caps in BAT, of silver foil caps in AN might be the examples. Melquiad...

Romy, would you explain / help me better understand how you implemented the HP filter in Melquiades?The schematic shows a series cap after the first tube stage (C3 and C4 in the schematic). I think these are the first-order HP filters, correct?Quest...

Hi Romy,i want to use the 6E6P-DR (triode mode) as driver in my tube 45 amp.I use a D3A (triode mode) with Anode choke at 180V, 12mA. Grid 2 is connected via 50 Ohm resistor to anode. Grid 3 (pin 8) is connected to cathode.The 6E6P-DR (also 6E6P-E) a...

[quote user="Romy the Cat"]I do not exactly comfortable with oxric’s preoccupation with “parts”...There is nothing wrong with the selection of the parts that I provided; in fact I personal feel that they were the right parts at that time. So, with th...

[quote user="KOTriode"]Romy,I looked at your Melq schematic : http://www.goodsoundclub.com/PDF/Melquiades_SET.pdf regarding the 6E5P bias. Would it be simpler to use two alkaline battery in place of R5 to provide 3V , or 3 Rechargeable for 3.6V ...
|
[quote user="KOTriode"]Ok, I just read your "Melquides Remote biasing". This technic can not be duplicate in my amp due to DC coupling, the C3G (I dont use 6E5P) driver stage basically adjust the 6C33C current in the output stage. Just for curiosity,...

I'm thinking about trying to put together a Melquiades amplifier for myself. I printed out a copy of the schematic (thanks for sharing). I have a simple early question. Both the 12.6 and 6.3V windings for the filaments are shown as being center taped...

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?...

If to look at the Melquiades schematic in the channel “A” you will see 78H first order low pass filter.
http://www.goodsoundclub.com/PDF/6-Chennal_Melquiades_DSET_Amplifier.pdf
The low-pass filter in Milq and the low-pass filters generally is great...

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...

[quote user="Chirag"]The 6E5P is an interesting device (I did some research after you dropped the "tetrode" hint and bought a few :-)), but the bias scheme with the OA2's is still incomprehensible to me. [/quote]Ok, I will try to explain.

[quote user="drdna"] Not that the sound is bad, but my technique must be bad. Because sometimes during the day the sound will get really particularly bad, even to the point that it sounds like clouds are passing by over the music, if you unders...

Hi, Global.
Leaving aside the unnecessary to be called notion of Melquiades vs. Lamm I would return to the essence of the thread: what changes are necessary in schematic if it goes for 220V. I do not think that any changes would be necessary. All tr...

Hi Roman et al!Allow me to introduce myself. I have followed with amusement Romy the Cat for many years. He is ascerbic and ultracritical, but he does know audio. We share many tastes, like the Koetsu Onyx Platinum foir instance, on...

Dear Romy,
Thank you for the commentary and the advice with regards to the need to have a COGNITIVE ORDER OF SUCCESSION and to test with another speaker in situ first.
Given the varying degrees of how different individuals process COGNITI...

Regarding the "complexity" of these amps :
Not being a DIY electronics guy, the Melquiades schematic makes me want to reach for a cigarette... However, naive fool that I am, having no formal training in electronics, I look at it and think to mysel...

Romy, thank-you for your help so far. Unfortunately I now have some more hopefully simple questions regarding the "pre-final" schematic from your "6 Channel
Melquiades" thread (see below). 1.
Do you have a “final version” of the
schematic any...
