Just ran into one of these, it has U508 burned and blown, along with R333, R233, and R559.

Someone has been into this thing before, all the outputs have been replaced by someone else along with the 2 drivers and a few more resistors.

They forgot to do these parts i guess.

Here is the problem. the resistors are burnt beyond recognition so i cant figure out what the values are.

Also the U508 are one of the ICs with the scratched off numbers, but the IC is fried and blown. Does anyone know what this IC is?

While the LM361 is out of the circuit and after replacing all known defective components, connect a jumper between the two points indicated on the attached photo. When you power the amp up, there should be absolutely no DC on the center legs of the outputs.
