On the bench is a Fender Frontman 212R that is distorting on both inputs. Inject a signal in the PowerAmp in and still distorted. I traced it down to this...
on U6 i get a good signal on pins 1,2,3,5 and 6 but distorted on 7. I swapped out the U6 but no go. My voltage on TP29 is off too. I'm getting almost nothing there. I'm getting correct voltages on either side of D38/39. And I get distorted signal on both inputs of Q9/10.
Any suggestions on why this thing is distorting only on pin7 of U6?
thanks in advance!
