Hi I have a Punch 200 DSM on the bench, it's had the input board recapped and all 10uf capacitors replaced.
Left channel has clean audio,
Right channel has 19.9v dc on negative terminal
R131 runs hot
The amp is stable at idle and doesn't draw excessive current
Any help appreciated, thanks in advance

Do you have clean audio with, essentially 0v DC, on pin 1 of one output driver board and pin 2 of the other output driver board?
Did it have this problem before recapping?

On C203, is the DCV greater (farther from 0v) on the driver board side of the cap or on the preamp side of the cap?
The cap sits behind the treble boost potentiometer, the negative terminal faces the driver board and positive terminal faces towards the treble pot
Pre amp side is -0.110v positive trace leads to preamp board also rca shield
Driver board side is -0.031v Negative trace leads to driver board
Driver board side is -0.031v Negative trace leads to driver board
