The various parts have various levels of distortion. You can use the cheapest one.

Output pins of the op-amps, not the output transistors.

No. I need you to measure the DC voltage on the output pins of all of the 8-pin op-amps in the amplifier. The output pins are 1 and 7. Pin 1 is near the white do on the board.

Please don't post in a repair thread that was started by someone else unless you are trying to help them.

Contact MTX. They will give you the resistor values.
