The first listening impressions tempted me to change it's name in headache. Humm was too loud. But using a separate transformer for the B+ and an additional RC filter solved that problem. No humm left.

Now, after proto nr 3, the sound is as good as can be. Subjective testing with my iPod tells me this is a good amplifier.

I need to do some tests to determine whether both tubes are more or less equal (and both channels are therefore equally loud).

Further testing will be done as soon as I finish the amp.
