Change all of the outputs as well.

You also need to check all of the MPSU07/57 drivers to see how many have failed.

Thanks again Perry. I checked all mpsu 07 and 57's and 2 of the 07's are burnt thinking about replacing all the 07's with a part from digikey they show better ratings the digikey part number is
TIP 110gos-nd and i have the mpsu 57's in stock now the other problem im facing is i have to find someone with the internal speaker plug that solders to the board and the power/clipping lights and both push switches for the eq and mono since the person i bought it from cut all that stuff out of the amp. Personaly makes me sick that someone dose this to the older amps that are of this quality but thanks again I really appericate your help

Allied electronics sells the plug you need for the speaker molex. It is on page 225 of their latest catalog. I will try to remember to get you a part number tonight.

The TIp110 isn't a good sub for the MPSU07.

Until you can find the switches, you can use jumpers to connect each of the individual circuits.
