Hi, I have a question: I recently bought a second-hand PC9501N amplifier. Both channels sound ok, but there is a difference of 3db between channels A and B, (according to the dB meter) and a difference of 0,5V between outputs (applying the same signal, despite of being in stereo, mono or bridge). No clipping or distortion. No shorts or open transistors. The power supply delivers the same voltage to the 2 channels. Why does this occur? Maybe I should adjust the bias? Thanks in advance

I have a PS3500 that powers up but doesn't show any signal going to it, and nothing from the outputs! Could this be the same issue??

no - P3500S have a torroidial transfromer. Your issue sounds more like a bad opamp or muting circuit issue - easy to trace and fix.
