hej!
i have set up both channels in my passive eq with point to point tube gain stages.
looking at the outputs of the OTs i get quite different square waveforms and more resonance in one of them. one have bandwidth to about 55Khz and the other about 85Khz...
ive read comments about bad layouts can cause funny stuff but i dont know what to suspect, where are the sensitive parts. its a two stage circuit with global NFB.
is there some literature on the subject anywhere?
