Hello, I recently bought an old commie amp from a thrift shop with a burnt output channel. I replaced the faulty transistors with equivalent ones ( the second transistors in the darlington pairs were fully shorted), also checked the rest of the components wich seemed ok. The problem is that the new transistors shorted instantly and I cannot figure out the reason. Also, while running it with the functioning channel only with the balance not fully on the good output, a resistor (R435) started smoking on the faulty channel ( with the shorted transistors removed). Any suggestions? The electrical diagram is attached.
