Thanks very much for your prompt, courteous and informative reply!My thought about the crossover design for the EdgarHorn was due to a number of things:1. This particular EdgarHorn is being sold to make way for a Cain & Cain speaker which i...

[quote user="Romy the Cat"]Still, doing whatever crazy and Macondo-dedicated things I will be doing with one stage I will have my full-range Milq as a tested reference trying to get result no worse then the one that I got from a “default” Melquiades ...

With the project of the 6-chennal Super Melquiades is about to hit its final stage I might to review my summarizing observations. The 6-chennals Macondo is driven by 6-chennals dedicated DSET Melquiades, that looks like properly orgies for the job. T...

[quote user="Antonio J."] The builder regards VR1 more like an "offset to 0" adjuster than a bias control for the 6E5P since its working range is quite narrow. He asked me to know from you if along the 6E5P's lifespan it needs further adjustment...

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...

[quote user="hagtech"] It's difficult for me to guess exactly what the possible sonic effects of the ripples would be. I see a tube operating at a fixed point, having a particular distortion spectrum. Say -42dB 2nd harmonic. Then, t...

Since the last week, when I put the left 6-way Super Milq in duty I am hardly wiling start working on the right channel. I left it as is for a while, screw it.. I am too lazy and not in a mood to do it for now… I found recently a space to put my tape...

This weekend I discover interesting phenomena on which I did not pay attention before. The Montrealian Charles Dutoit conducted this weekend Boston symphony. I was listening the broadcast, recording it as usually. It was very bad. The BSO wind sectio...

I’m not convinced at this point that it is good – I need to see it more in context of everything else - but the initial results are very promising. What I do now, I keep the compression Fane 8M in horn but I very dramatically increase dumping of it...

Here is the last “real” version of the super Milq input with all filters. The rectors are not common denominated yet, them will be later but it will be already it. I can wait to hear the thing.

I made some power measurement of the Super Milq, to my surprise it is not so much hungry east as I expected. During the startup, what the B+ begins to charge the large capacitors the amp sucks 8,6A. When the amps is fully charge, heated and in it cru...

Can someone help me to calculate the input impedance of the 6-chaenal Milq?It is cannot be measured as a regular DC impedance as it is affected by the active impedance and the by positive and negative voltages from the bias supply and the bias compen...
|
|
Today the second 6-way Super Milq is done in bench version and looks like fully functional. I actually did listen all channels with a full range speaker – they sound fine. All operational parameters are there and look like I will leave the amp to run...
|
|
To my surprise it is going along not painful. I do it a half hour per day – only when I am in a mood - and I do not feel abusive with it at all. At this point the half of the bias chain of the third of the filters have installed. If it go further so ...

HiI'm now at a stage of building the chassis for full range Milq.It will be a two chassis,one power supply and one signal,very similar to Romys super Milq layout.The two will be connected by two separate cables AC and DC.A few questions please1.How a...

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...

Ok, I completely disassembled one of the Super Milqs and physically injected extra 3 channels. It looks like everything is all right real-estate wise, still I would prefer of course to have more space….
As now the amp is completely shattered ...

That sucks. I use to have a box of perhaps a dozen of YO186 but I did not see it for a while, pretty much from the time I moved to new house. I was listening today some of my “critical” reference stuff and concluded with very high certainty that my M...

Playing recently with setting up the new 6-ch Milq I again got an interesting feeling about my Fundamentals Channel. The in Injection Channel partially overrides some benefit of the Fundamentals Channel and I have a partial feeling that it would be p...

OK, I have conceptualized what I need for the tweeter amp. It will be MilqEZ – the same Milq one with 6C19P at output. I will use the Super Melquiades power supplies but the HF channels will host own last caps of the filters and own bias of the both ...

[quote user="cv"]Not to start a pissing contest, but how are they wired (series/parallel?), and with what voltage across them? Something just can't be right; the makers spec is 88db / 2.83V, which is over 1W. Unless it's uniquely smooth room gain wit...

Ham-set,I think you are digging a hole in a wrong place. Regardless of any SiC alleged or actual problems I absolutely assure that the ham you have has absolutely nothing to do with type of the diodes you use but only come from grounding, shielding a...
|

DA, I would not use any switched power supply, not to mention that they do not need to be regulated for LEDs, relays and fans. I do not know if you build a full range Milq or more complicated multi-channel version. If it is a full range Milq with onl...

Running the fully closed Super Milq for a few days I noted some amassing qualities that took the HF performance of Super Melquiades even further then Melquiades. This quality consists of a complete absent of any king of glitz and very atypical for th...

I was slowing mingling the conversion of the power supplied of my second Super Milq from 3 channels into 6 channels and I ask myself: is anything in that amp is made in the way that would allow me to close it up and never review it. Sure if I move in...
|
|
Another decision that I need to make about the new Super Milq. I have MF and Fundamental Channels around the Vitavox S2 drivers that will be driven directly from the single-stage amplifiers, with the crossovers and attenuators sitting at amplifier li...

[quote user="Romy the Cat"]If you read the very important post: http://www.GoodSoundClub.com/TreeItem.aspx?PostID=5255 then might understand that it lead to a painful research on the subject. I have ton of data now and many experiments done. If ...
|

Thanks, Jim, and thanks to everyone who replied in direct emails. Summarizing what was advised to me it looks like as now the input impedance of the amp is around 4.5K. That was roughly what I would like to have, though I would like to go even furthe...

Here is a stupid need of DIY audio level. As many of you know am big lover of Nichicon electrolytic capacitors, even their lowers grade sounds right to me and never made to think about anything better. Still the Nichicon never stopped to surprise me....
