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 improper amount of “density” of sound at HF. Interesting that the full range Milq had no such a problem. Also, the HF channels in the Super Milq are not high-passable for whatever reasons. The only different between the Super Milq and full range Milq is the output transformer, use of half of the tube of the last cap in B+. I observed the high amount of capacitance in B+ make HF “hard”. I am planning to go from 15.000uf to 1000-2000 and change output transformer. In addition I presume that the way in which I used my current HF OPTS was a bad way to do it. I use 0.9H transformer with 4 primaries and 8 secondaryes and in order to load the tube properly I use one of the primary as secondary… As I was informed it is not kosher way to get the best out of transformer in case of serious demands.

Glad to feel that this problem was resoled by “small blood”. I loaded the 6C33CD more heavily for HF channel and it made all magic. The remedy turned out to be a magical as the HF channel of Super Milq limitedly become as good, actually even better, then the full range Melquiades was. It has that sense of softness but at the same time the sense of extreme HF deficiency. Wonderful, absolutely wonderful. You are saying about making mistakes… I had 1.5 year running the HF channel in less perfect configuration. I was mildly complain about it but had no idea WHY it might be. The interesting thing is that my current HF loading (~5R) is kind of too soft for ½ 6C33C. However, the HF channel drive very “fast” Vitavox S2 and has very “fast” core. All together it works very nicely…

Now I am a happy pussy ready to be critical about my new coming tweeter.
