so i decided to rebuild my stereo over the weekend (voice of music old tube model) and i put in mostly solen coupling caps and vitaminQ's to the output tubes, and the thing just sounds awesome BUT! i still get this same noise off the plates of the phase splitters! it has nothing to do with them coupling to the output tubes, as they generate this hum on their own. also its only in the second triode and not the first.
its 60/120hz and is affected by the hum balance, but balancing doesnt cure the problem. the 6eu7's are ac filament, can they be dc? it does this even with no input signal. maybe like 1.4Vrms AC of noise... really damn anoying... the thing is the power tubes run quiet as hell and the whole thing has been recapped....
ideas anyone??
canyou clean up an ac filament supply??
thanks!!
