I've seen your posts here and elsewhere. They all seem to be of similar
quality. I have been designing, building and _listening to_ audio
amplifiers for about 60 years and the plain fact is that tube amps just
don't do a good job especially at very low or very high frequencies.
Almost acceptable THD is possible at 1 KHz matbe even up to 5 or 10 but
then maybe you can't hear anything above that.
