Are there any other problems?
If not, we'll have to work our way back to solve other problems.
Does the gain pot work normally?

Both jumpers on the right side are connected to 1 end of R137
do you think the problem is in that area of the amp or some where else

It looks like voltage is being driven back into the op-amp. Do you see any 12v sources in that area?
I pulled the ic and cleaned the board with acetone and the voltage is back down to 0.00 volts . But I had this same issue earlier in the thread when troubling shooting and the voltage same back and caused this issue .
At this point I will clean the board some more and check the components in the area and post back

I also noticed I have 13 volts on the top row right side of the jumpers for master slave switch
I replaced R137,138 and U106 .
I reinstalled the phase switch and so far the voltage on pin 1 of U106 is still at 0.00 volts .
So should I install the master slave switch and see if the voltage remains at 0 or check more components

Ok I replaced U106 R137,138 and reinstalled the phase switch and the voltage on pin 1 remains at 0.00 volts .
If I reinstall the master/slave switch the 13 volts comes back on pin 1 .
So do I have to backtrack from the master/slave switch to see where the voltage is coming from ?
