I love my 1020, so I picked this up recently for a second receiver. Fully tested upon getting home and the right channel only output distortion, not even distorted music, just buzzes to the beat. Thorough de-oxit didn't fix it. Needs caps, but I wouldn't think caps would cause that dramatic of a distortion. Output transistors tested no shorts. Then I was checking voltages on the OTs and.. slipped, shorting one left channel momentarily. Suddenly both channels came in clear. It played perfectly for maybe 10 minutes, then quickly degraded back to where it was with the right channel distorted. So, what could this be? I'm familiar with the grounding issues on these CRs, so I will start there, but any other thoughts? Thanks!
