And here are some photos!
Right amp board before, you can see the burned out resistors from browned heat wraps over them.

I had to customize the boards a little to fit the new relay in. The photos below are of the right amp board.
I first checked the fit and drilled some new holes using a 1/16" bit, I was a little off on the last two on the far right, they should have been even with the others
Soldering it in, I scraped some the green coating off of the trace around where the new holes were so the solder would stick and soldered it in. The output wire that goes to the speaker terminal needs to be moved from pin 12 to pin 13, also needed are two jumpers, one, the green wire, jumps the 48VDC for the relay over to the new relay position and two, the bare wire jumper, connects pin 13 to pin 12 so the meter drive circuit (pin 10) works, as pin 10 is directly connected to pin 12 but not pin 13.
And it's all together again!
All 8 outputs have been replaced as well. I powered it up on a DBT after each amp board and the relays worked perfectly, glorious music greeted me when I tried it for the first time.
The offset was rock steady after being on for about 5-10 minutes and even when first powered on it doesn't jump around, it just slowly drops until it reaches the steady point.
