Pulling the rectifiers will isolate the audio section but that's not likely going to accomplish anything because it's doing it with no remote voltage applied.

What's the DC resistance across the B+ and ground terminals (disconnect the 12v power supply from the amp before measuring the resistance)?

Pin 16 is causing pin 3 to go high which is shutting down the supply. Is there an op-amp near the 494?
