[quote user="Antonio J."] This is to me the most difficult problem to solve. For example, you may decide that your problem is a lack of spaciousness, which may be due to a lack of correct delay, wrong bass response, poor detail retrieval or whatever....

[quote user="Romy the Cat"]The HF channel of the Super Melquiades should be revised. Something is wrong in there and it does not sound as I would like to. It mostly relates to imp...

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...

[quote user="ml8"]So sometimes i just wonder why do you need 6C33C at all, with your high-sensitive speakers.[/quote]
This thread is a derivation of the “5 Channel Version of Melquiades” thread:

My project to add 3 one-stages channels to Super Melquiades look like progressing (it means I will have the new 15,5:1output transformers very soon) and in context of upcoming changes and, after long consideration and some tests, I desire...

[quote user="Jordi"] If I build them ... I'm going to use different cases. Man, the one's shown are U-G-L-Y. [/quote]
To my view the chassis for the full-range Melquiades is not ugly, in fact I do appreciate the design immensely, functionally a...

There is a number of people who asked me if I build Melquiades or if I know anyone who does it. I do not build them for sale and I do not know currently any technician who would offer his services to build Melquiades.
I know some folks who might be ...

What would I do if I move to a much larger room and the power of Milq’s full 6C33C would not be enough? Surely it would be possible to go for transmission tubes but they all high plate impedance and high voltage. If I parallel all my bass drivers and...

Here is the general specification for the parts that I used. The selection of the parts implies some liberty of course. It will be your amp after all, not mine - do whatever you wish. In some case when I feel that requirement is critical I will stres...

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:

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...

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...
|
|
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...

Consider a triode connected 13E1. 95W dissipation, will probably work beautifully with the existing OPT if you adjust the gap down and if you can rewire your arrays to present a somewhat higher impedance.Something like 400V-450V / 200mA-ish will ...

Hi Decoud:I cannot but help noticing that you are based in the UK (like myself presently), and since I am not the only one considering building the Melquiades at some point, it might be of interest to many readers, if you have the time and inclinatio...

Thanks for comment, decoud. If you live with Melquiades for a while then you might discover that it will moderate your listening interests with time. I do not know what you are listening now but be if you spend substantial amount of time with Milq th...

[quote user="Romy the Cat"]The concept of self-testing boot cycle is nice one but it for sure could not be done during the amp booting. Some tubes do need to warm up and reach the cruse temperature in order to be tested, some do not. Some tunes (lik...

Hi Romy,One my channels started emitting intermittent loud popping sounds, once every few minutes or so, and on inspection the current (set at 240mA) was in excess of 300 (my meters top out at 300). Assuming it is a tube problem I replaced the 6c33c,...

Ok, it took 2.5 hours to mount the transformers and chokes. The transformers above are filament transformer and high voltage transformer. (The super Melq has all high voltages coils as separate transformers). The 3 chokes above are input chokes for f...

OK, the next step is kind of done. All transformers and chokes are done form “outside” of the amp (under the bulge). I have attached the capacitors and the output transformer to the “inside”. This silicone attachment that for the computer grade...

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...

I am not a DIYer and have no skills nor knowledge to build the Melquiades, so I contacted a technician here to have one built. He said he could make it and stated the cost at around 3000USD including his working time. He suggested some changes in the...

It hard at this point to sat anything defiantly about the Super Melquiades sound. Positively to derive the speakers directly from amp with no speaker-level crossover does provide multiple and multiple benefits. So, Even if to subtract all other “diff...
