I found lots of bad caps in mine. I used the Dick Smith, in-circuit ESR Meter to find them.
It took longer to get the unit apart than it did to find the caps. Excellent meter!
First of all, check all caps in the power supply section (see pics) for high resistance (ESR)
or open.
The caps that gave me trouble were: C206, C207, C214, C215, C218, C219, C220 and C221.
Another problem with this amp was R201 and R202, they were open. Also, Check the solder
at D657 and D658.
That about covers it!
Good luck.
I have some pictures if you need them...
