Measure the DC voltage on the output pins of the op-amps near the RCA end of the board. Do any have more than a few millivolts of DC? If so, does the offset vary significantly when adjusting the gain?
What is the DC voltage on pins 1 and 8 of U6?
Use the RCA shield as the reference (black meter probe on RCA shield).
