Is it normal to read 22 ohms between legs 1 and 3 for the outputs?
Just wondering because the left channel the outputs get hot within 2 secs and they all test fine off the board the drivers also all test fine of the board
If you can't find any defective transistors, the servo op-amp may have failed. It's the TL071 that has two 1M ohm resistors connected to its input terminals.
For the 1M ohm resistor connected to pin 3, confirm that you read 0 ohms from the end of the resistor that's not connected to pin 3 to the non-bridging terminals.
