A while back I posted that my SCA-35 had a hum problem and the consensus is that it was because of unmatched power tubes. I have a matched quad on order, but meanwhile the amp has suddenly gone very soft in one channel and will not bias at all on that side. So that may be the underlying cause, which now needs to be sorted.
I got this amp in a messed up non-working condition with an old, disconnected preamp board, Chinese clone main boards and a powersupply board from Audioregenesis, pre EFB.
I went through the amp carefully with help from here and very kind help from George Ronnenkamp and added a P2P EFB mod. I am now thinking of doing a complete rebuild using all of Dave's nice SCA-35 replacement boards. I like the controls and compact phono stage, but I hear such good things about the ST-35. Should I just make it into a ST-35 instead?
