I agree with Perry I would also change Q2, Q3, Q4, Q5 the driver transistors for the power supply.
Sometimes the 1N5336B's will short when the power supply goes they are D4 and D5 you can remove them from the circuit and power up the amp safely only if they are shorted and the amp wont power up.
Also check all the 10uf 16v aluminum caps on the board good chance some are leaky, and check the 2200uf 35v rail caps they can leak also "sometimes".
Good Luck!!!!
