Hello sir,
I'm getting ready to put the lid of this repaired PA amp. However I like to check or do the calibration before I send it off. I have the the schematic but it doesn't print the adjustment procedure. I would like to apply for some guidance from season repairer on which test point to probe on and its idle voltage. On the board there's TP1,TP2,TP2,TP3,TP4 and TP5. On the circuit diagram TP4 is missing.
I hereby enclosed some pictures and schematic. Thank you in advance sir.🙂
