What might be very interesting also is to learn what DC coupling in power amps would do generally in term of Sound.
The first time I thought about it was a few years back when ...

A few days ago I decided to learn how the new Melq sound and made a quick speaker level crossover for one of my Macondo’s channels, putting the new built Melquiades to drive the acoustic systems that the SET meant to drive (Before it was 82dB and 88d...

Thanks Romy!I went with two tiers as I do not have much space between the speakers and the side walls as I have a 2.5M cabinet on the front wall.I named my amp Koshka as I always felt Koshka made a contribution to the development of the Melquiades an...

Yep, it looks, like very close to “it” design-wise. http://www.studiomaudio.info/loftinwhite.htmlIn the way this amp is one of the manifestations of Loftin-White DC-coupled but it has some own things. The driver stage is the Melquiades Tube to k...

Here is a semi-final draft of 6-chennals Melquiades Power Supply. Since I use my site pretty much as a notebook would like to have the diagraph posted in this thread for my personal references.

Ah, last night, after midnight I picked in McMaster-Carr some elements for my proposed Supper Melq rack. Thy shipped it UPS ground and I had it delivered that same day! How they do it? Anyhow, I connected two shelves with 4 x 12” by 5/8” rods. I tigh...

[quote user="hagtech"] Iwas going to ask you about that funny looking damping material. Then you explained it at bottom of post. Very clever to use mouse pads! Lately I've been using cork & buna rubber sheets from McMaster-Carr....

Antonio,You should expect to hear just the music. In explaining the effect of this process in words, I am in a simmilar position to Romy with his Melquiades amplifiers.Most speakers sound just fine, to those who are used to them. We have, in our sens...

The Super Melquiades Amplifier is essentially the 3 parallel running Melquiades amplifiers optimized for driving my Macondo Acoustic System, with line-level or inner-stage filters. This SET uses a full 6C33C at LF output and ½ of 6C33C for HF and MF ...

I have no “apparent aversion” to anything at this point and I would accept absolutely anything that would deliver a result, no mater how crazy it would be. I do not talk even about the X-factors or about anything “kinky” but only about a plane transp...

[quote user="Wojtek"]I'll experiment with the PSU a little. The transformes have only 1 Ohm DCR and total supply impedance for a channel would be ~ 45 Ohm (with two chokes in series) Imput choke looks like can take 1 A current! [/quote]

Perrew,
LCR is not active at all; it is the very same passive EQ as your RC? I think you a bit confused with terminology. The main logical explanation (there are many of them) is that capacitive filtration is very bad one and need to be minimi...

[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...

[quote user="drdna"] I can tell you already it will work. I have experimented extensively with adding lengths of metal to cables. It works well, but you can do a lot more by fine-tuning the amount of metal and in fact adjusting it slightly from l...

[quote user="Romy the Cat"]Well, they technically not Lpads but juts regular attenuators
even though they connected in “protective mode”. You can go with stabilized impedance
to maintain the high pass filter over the coupling capacitor to work prop...

[quote user="anthony"]In the 6 Channel Version of Super Melquiades
thread at post #89 you mention trouble you
were having with some NC relays that you were using to disconnect some power
supply bleeder resistors when the amp was turned on. When t...

[quote user="Romy the Cat"]
I do not know why Placette
does not work in your situation. You do not have enough volume? If it is the
case then you might have too low gains in your front end. All my front ends
have very high gain: Bidat, Lavry, my...

This weekend a friend of mine visited me to listen my playback and there was a very illustrative occurrence. We listening my audio and everything was like it should be in the program. He was visiting my last time in 2002-2003, before the Macondo was ...

[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) ...

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="AnonymousUser"]I am thinking of launching into building or rather having buitl by a techie friend a pair of melquiades. Could you tell me more about the cost of building a pair of these amps? then how do they compare to other amps? I mea...

Since I know about a few ongoing attempts out there by different people to build Melquiades I would like to share with some of my observations regarding corrections, simplification and possible modifications of Melquiades amplifier.
Obviously you ha...

Thanks, Guy, for your explanations. Still those “have less inertia and are able to change direction more quickly” I feel has more to do with out intellectual visualization of how DHT work. I do not think that inertia would be correct concept an...

[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]

[quote user="hagtech"]I have not tried this tube yet. It might push the limits of the tester. The 6.3V heater current supply is nominally rated at 5 amps. It might be ok to push it to 6.6 amps. I have to think about this, make...

I have given a lot of thoughts to this topic lately and have a number of conversations with various people about the subject. A friend of mine from Europe, who is currently at fitness protection program, suggested that:

[quote user="anthony"]To mirror your

It is impossible to make two amp with the same quality with such big difference in output tubes , the transformer design are vastly different, a 10Kohm transformer would never have a good bandwidth as a 600ohm transformer. I just have to experime...
