Thanks for your input. I may have vastly overestimated my troubleshooting skills!
I don't know if my last message was sent so..
1) The two main filters are an easily reversible fix. They are still in place
2) Should I start with Q1 on the 5065 or start testing the power transistors Q10 - Q13 first?
3) With the 3 wire connector plugged in to 5065 I measure about 43mV on the output jack when the amp is on
I've also replaced the power cable with a 3 pronged cause I was getting zapped while holding the chassis and unplugging the input jack.
