Front channels are fine, rear channels pop and crackle and are distorted. injected
100 hz signal thru 1st and 2nd ops, checked with scope, a little fuzzy but audio ok. No dc on speakers. Also used audio tracer to check op's
Signal at output amplified but sine cuts out as if the poping is effecting signal. I have replaced front end 10uf caps, and 100uf caps at output, no good. I have noise from rca ground to center pin?? Any advice please.
