Hm, I do not know men, but it des not work. Over the last few years I have tried the ordinal metal diaphragm 4 or 5 times and not with the Super Melquiades it is the most successful try but I still feel than it is not the sound that I would like to g...

Anthony, I visited you thread and glance the progress you
are going with Milq DSET. I do not exactly how you feel, I went over it myself.
Let me to tell you how I dealt with what your experience. I am not sure that my
dealing with the problem is a...

The more I conceptualize my view about tweeters the more I like sound of my playback without it. The last night there was a San Francisco broadcast with estimable Tilson Thomas on podium and I was shocked with stunning SFO’s tone. As many times I hea...

This week I will be trying to address why the Milq midbass is clipping. This is very interesting one. Currently the Melquiades LF channel uses an output transformer 700R to 5R or 11.83 to 1. I thought before that I have much lower ratio, like 5:1 bu...

The name of the post I took from the 32th chapter of M. Bulgakov’s Master and Margarita, so from there will be the epigraph for this post:

Last night I was listening Zubin Mehta’s recording of Bruckner’s Symphony No.9. It was his first recoding from 1966 with Vienna. I am not a big fun of this performance all together but it has spectacular first movement. It played superbly slow and s...

I was replacing transformers in the Super Milq HF channels and while I was doing it I decided to perform a minor maintenance on the amp. One of the amp’s fans developed a “flat” in it bearing and created a very minor “step”. I order a replaceme...

You are correct about the load matching, for the Super Mild LF channel a half-Ohm of loading change bass quite dramatically. Still, the idea was to make this SET completely without any intentionally implemented feedback. It is juts not necessar...

Chris,
when I got those large 7Hz-1kHz transformers I soldered one of them in my regular Melquiades and listed what it did. Besides all necessary bass benefits I decided to see how plate current would behave if I have no limitations for core satura...

[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.&nb...

I have been contemplating for a week if I need to drain the power caps in my new revision of my power amp. The benefits to live the voltage in there is the cap continue formatting what the amp of off and it minimize the need to break-in or to train t...

Ok, here is the final frequency response for each Super Milq channel. The souse was Denon CD player that rolls off a little atop. I did not measure the tweeter as I have no tweeters transformer plugged in yet. All secondary in amp are grounded. The m...

This weekend the new 6-chenal Milq is not finished yet design-vise but functionally is already “there”. The amp was good enough to play with other 3-chenal Milq. Firstly for the last month I was able to listen full stereo from Macondo…. I spend some ...

In fact am not only planning to try an electrolytic capacitor as the LF Milq’s coupling (if I found one with low linkage capacitance) but I would also planning to try the “my proprietary” cooked capacitors. I have to admit that it sounds very s...

As some of you know I’m playing last couple days with Red 10” Tannoys from 60s. My selection of 10” was not accidental -I would like to get as less as possible of that “Tannoy bass” but I did run very far the “Reds” turned out to have 27Hz open...

Jim, I have sent you the tubes – it might be an interesting journey.

Guys,
Thanks, for your help with all my HF channel frustration.
The saga is not over. The latest update is the following:
The “secured” Cubes 950 (1000pF and 500pF) were placed between the Milq’s HF channel and the result was dissatisfying. The so...
