Ok I will check and clean the connectors. I have a fast drying electronic equipment cleaner that says it removes oxides. Should I just by a can of Deoxit
I've measured the voltage at R16 & R15 9.8V which seems to be expected. At R16 and R17 and pin 1 of Q3 I measure -.7V, the schematic indicates 7.1V (If I'm reading that correctly). Could the IC or the pots bring this voltage down? If R17 connects the transistor side to the IC side, could I isolate the transistors from the IC to verify Q3? Or is R17 and everything after it needed the test Q3 voltages?. Or would you forget about all that and change the chips?
1)Is there a replacement I can use for the IC?
2)Is an op-amp short causing -10.72V on pin 13 and -11.48V on pin1?
3)Have you seen two blown op-amp ICs in the same amp before?
4)Could an input have caused this?
Here are the voltages in a more readable format.
