Interesting. The chips in mine say JRC5532, which I assumed was just a JRC clone of the NE5532. I have a tube of LM4562's sitting around, they're rated for +-17v, though the spec sheet does say "Absolute Maximum 36V", which I'm gonna assume is equivalent of +-18V. I Guess I'm gonna try and tone...

Got a question I'm hoping @DBaldock9 or someone might be able to help me out with. TL;DR: Could a bad opamp make the left channel silent, but only in balanced output mode? I've had my p20 for about a week now, and I am truly in love with it. I had read most of this thread before I bought it...
