Yes, Jessie, but in case you decide to go for DSET, would it be multi-channel Melquiades or anything else, then your consideration for type and topology of the lower bass would greatly dictate requirements for your DSET. If your lower bass channels r...

My new 20L and 30K L-pads for the 6-chenals Super Melquiades’ tweeters and Injection channels. They are 24dB down by 1dB, made on the Elma Rotary switches and stuffed with unavoidable RB60 resistors. I did not want to burn my fingers and outsourced t...

Hi Bud,Thanks for the pointers; I already have a pair of vertically sectioned cores wound from a while back, on white nylon (ugh?!) . Not remotely optimal, but if the concept works I will definitely have to try something along your lines. The tip reg...

Funny, I was just thinking about battery powering of amps... I know you have identified that the problem is more with the sources, but it would be interesting and quite feasible with the Melquiades and other components... wouldn't want to try it...

Romy,As it happens, I approached N-Set as I thought I might suggest some transformer winders who might be more reliable than Peter of Tribute Audio...As an aside I wanted to find out if the fish market in Barcelona is as good as it used to be the las...

Further looking at where I would like to take the new 6-chennal version of the Super Milq I am contemplating a new revision of my bass channel output transformer. Currently I have Jack Elliano’s made 450mA, large, single section LF transformer that b...

Thank you both for your thoughts. The space is interesting: not a cellar, but a sleeping area just big enough to fit a super king size bed, with one of the walls being half open, so it would not pressurize quite like a fully sealed room. Further, it ...

The 3-channel version of the Melquiades on steroids - the Super Melquiades SET is over. There are still some minor adjustments doing on but they mostly take place outside of the Melquiades. I think in a week or two the amps with the mated speakers wi...

Thank you Romy,
<<The multiamping with Super Melquiades was made with intend to optimize the output transformers and to eliminate the interference between the inductance of the upper bass driver’s coil and the MF driver. I still use the speake...

[quote user="Romy the Cat"] One of the things that solicited me to try the APS unit was the assurance of the APS guy (Richard) that what I run ASP unit from internal battery + regeneration vs. the plugged in wall + regeneration ….I should hear no dif...

Wilson Audio Buys Rights to Romy's Amps and Speakers
Due to a reversal of fortune, Romy ("who would have thought all those air core capacitors would have added up to so much") sold all the schematics, rights, and designs of his Super Melquiades am...

R,Please excuse me if this is straying from the subject... feel free to move.Anyway, I was in NYC until Wednesday evening, and I assume I know what is motivating you to abandon Macondo/Melquiades in the hot summer months... what I don't understand is...

This is kind if funny as I never thought that I will go this way. I kind of have a need for an amplifier. For a normal full range amplifiers that would be able to drive conventional speakers. I really can’t use the Super Melquiades as it has the live...

[quote user="hagtech"] Yes, steel chassis can be both good and bad. It likes to conduct magnetic fields, so you have to treat things appropriately. A little spacing under a choke can go a long way. Otherise you have a 120Hz motor.&n...

The thread is derivation form the previous thread about the Dima's amplifier.I was trying to gradually approach better and better loudspeakers with the Zarathustra amplifier but today I decided to hit with the Zarathustra the pinnacle of low sen...

Eventually the right channel of the last revision of the 6-Channel Super Melquiades is complete. It has the new dedicated power supplies for single-stage amplifiers, the 600V Schottky rectification for 200V line and 1200V Schottky for 400V lines, the...

Somewhere in 1997-88 I bought a hundred 6C33C. I believe during those years the where more expensive then now and I paid around $7-8 per tube. Over the years burning the 6C33C in pair of VK-60 (8 tubes), two pair of Lamm ML2 (ML2), ML2 with Melquiade...
|

OK, first off all I have moved the latest posts to the “How to drive 6C33C” thread.
Regarding the operation point. My initial intention was to give Melquiades’ output as ML2 did: 175V, .310mA. What is important is to understand that for LF channel I...

I think we are all agreed that if time alignment and space were not issues, a bass horn would be the way to go.Now, I'm fairly convinced that the overwhelming benefit of horns in this range is the phase response, ie flat group delay vs frequency. Mos...

So, I did exactly how I described in the previous post and I returned back to the plastic suspension diaphragm sitting in the “new” drivers. I lost ~3dB sensitively and was forced to go back to 3uf crossover, exactly how I described in the beginning ...

If the S2 is completely decoupled (second order low-path at 1.5kz) then the rules of the game completely changed and the S2 behaved VERY different. I will wait until the dedicated channel of my Super Melquiades will be dr...
|
|
Righto then, I guess there is no reason not to try this, except that one of the original crossovers here is non-functioning (if I remember correctly), so if trialling in stereo I'll have to crossover in Melquiades. Should have the parts here to do t...

It is truly exciting time in my Macondo/ Melquiades biography. The 6-chennal Super Melquiades is done and fully operational. The 6-chennals of left Macondo speaker have build to the 6-chennal Milq. It “works” fine, not it is time to make it to sound ...
|
|
Yes, referring to my initial post on the thread: something in the Super Melquiades is very freaky. I did not use it for a week and this morning I tuned it on. The amp generally does not sound good for a first 10 minutes and reaches it’s stable ...
|
|
Obviously I have not carefully read everything you've written about Melquiades, mostly because I have just been stopped in my tracks by the ML2s, so I still have a lot to think about as it is. But if anything could "sell" Melquiades I'd guess i...
|

Those all things take too much space and the new amp for the “fundamental channel” does not really help the situation. I decided to convert the Super Melquiades into something that would have smaller footprint and position the control amplifier unit ...

[quote user="Bud"]I am about 3 weeks away from supplying 3 Kz ohm to 4,8 & 16 ohm SE outputs for 300b or 2A3 tubes to George Wright, of Wright Sound, and Gary Pimm of Pimm CCS fame (constant current controls to buffer stages from each other ...

[quote user="hagtech"]Hey, I never thought of this. You can run 1/2 the tube at a time! This actually puts it within the limits of the VacuTrace. I can test each side separately.[/quote]
..and while you do so you might discover one...

Hello Roman,Hola from Hong Kong! How are you? Haven't been here for long time. I have a question at the back of my mine for long time, and it may have been covered elsewhete in your blog before. I am asking it here but do point me to the thread if it...

Eventually I found hot to balance out the fundamental channel’s arm a 1 galloon bucket filed with led shot and Super Melquiades power supply do a good contra-mass.
I did not do a lot of listening but the very initial listing that I did are clear...
