Chris, at this point it is hard to say anything defiantly. Subjectively it sounds like the Super Milq has slightly less HF extension and transient then the regular Milq, although the output transformer of the HF channel of Super Milq runs higher and ...
|
|
Allo,Well, the divider may certainly be responsible for some softening of transients - in particualr, what values are you using there?Also, the received wisdom is that silver micas are created far from equal; no experience with them myself but I beli...

Hi Romy,Interesting scale you've come up with there. I would like you to take a look at a preamplifier from Korea called Silvaweld. I have found that with this preamp (model SWC 1000) in my system I can differentiate easily 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...
|
|
It is kind of pleasant and insulting at the same time. Insulting because I thought I know the Super Melquiades better then anyone else or at least was able to say about the Super Milq Sound whatever might be said. :-)
However, today my ego was sever...

This weekend I found some transformers in my storage and I put together the Baby Melquiades headphone amplifier. It turns out to be very cure little amp. It is 9'x9' but has all Milq’s incidents including the choke intuit supply for plates and t...

[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.
The...

So, I have decided I want to hear the Melquiades in my system. But, I do not have the ability to build one myself. I am looking to hire a skilled builder that would be interested in building the Melquiades for me.Contact me at: ...

hi-i have downloaded the circuit diagram for your amp but wondered if you have any photos of the "guts" so i can see how you laid yours out ?just a couple of questions1- R3 + R24-27 are shown not in bold print-why ?2-it says "look below for OPT"-?3-a...

For anyone interested in building a full range Melquiades I have a spare set of drilled aluminium cases, output and power transformers, offered at below cost. Apologies for sub-optimal photography. Please contact for more details.Regards, d ...

Hi,Every so often, someone contacts me and asks for some information about my plans (presently on hold) to build Melquiades Full-Range or D-Set, and whether I have a list of parts etc. My experience of trying to find a builder for Melquiades has not ...

Finalizing parts ordering for full range Melquiades and I have one thing with is unclear to me, the plate to grid resistor on the 6E5PIs R23 50R is this correct ?There is another R23 in the driver power supply .http://www.goodsoundclub.com/PDF/Me...
|

Well two power supply's ready and one full range amp hooked up.Nothing blew up so that's good!1) output stage 200mA /187V2) driver stage 205v (test point A) and -4.3v bais3)setting 0.000v on input is ok but not stable,some DC drift4) bais lines are l...
|
|
It looks good to me. As you can see I have left plenty of room to add a couple of more channels.The bottom level contains the power transformers and relays. The diode bridges hang from the the middle shelf and the chokes and filters are on the top ...

[quote user="jessie.dazzle"]Is this because of the way you are driving them?When testing my one completed mid-bass horn (AK151 into 40Hz Exponential with 8" throat), and powering it from an amp that drives everything from upper bass to HF, the output...
|
|
Since I got my stable and good quality electricity back I recalibrated my bass horn. Again, I set it up with very precisely and absolutely without any measurements, juts by ear, to sound exactly how I want it to sound. This is in a way my crown jewel...

[quote user="Romy the Cat"]Did anyone ever see the ready to do tube sockets adapaters that would let to pit the large gas tubes ingot the small sockets? Melquiades use 7-pin small 0A2 tubes but I would like to try the 0D3. They are the same 150V tube...

Building the Melquiades: #3
Spent last might 3 more hours to pile up in one of the Melq the rest of the parts. It looks like now all detachable parts are there. Whatever parts have no assess anymore are wired and the main ground is in place. Pretty ...
|
|
OK, I was looking today at the par of the new Melquiadeses posted above and realized they are too ugly to sit them in my room over the 4th July holydays. So, spending another fey hours I designed to end the project and put it behind me. I still do no...

(Quote from your post) "... by building any serious horns you will very fast overgrow the ML2's ability to be flexible." Yes, this is in fact what I meant by "limitations imposed by of a pair of SET amps such as the ML2s". Would it be possible to ada...

Best amplifier is the one that you just built…Yes, it is a common unfortunate law of Audio but the people who know me personally know that try do not behave according to this behavioral pattern. So, this weekend I decided to do try the new Melquiades...
|
|
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="drdna"]I am sadly missing the living presence in my system, and I thought from your description, that the Melquiades might be a solution [/quote]

[quote user="Romy the Cat"] I think this requires me to raise my voice as I feel that this presumption is very common and unfortunately very mistaken. Melquiades might NOT be a solution... A person should evolve his reference points and his assessmen...

[quote user="ml8"]So sometimes i just wonder why do you need 6C33C at all, with your high-sensitive speakers.[/quote]Actually it would be VERY interesting to expend on it sometimes… Why the Supper Melquiades could not be juts one powerful 2-stafes LF...

I did an interesting experiment today trying to learn if those Melquiades driver tubes have even gain. The Russian tubes are notorious to have very widely spreading specification, so….
I took 14 6E6P. Some of then were new, some used and some violen...

[quote user="RonyWeissman"]Hi romy, thanks for info. I am going to stick with the 2-stage plan then as it will not be DSET but full range and my mid-bass is somewhat barbaric at this point. I have found someone to build for me, though we ha...
|
|
[quote user="hagtech"] For a single driver, looks to me like you need an input signal of at least 3Vrms. A lot of linestages can do that, so a single tube power amp seems both reasonable and interesting. [/quote]
What actually I discovered the...

I was contemplating the 6 Channel Super Melquiades conversion – it will quite a revision – and I am slowly inclining to make it not 6 Channel but 7 channels…Anyhow, the post will not be about the needs of extra 7th channel but rather about one of the...
