Fisher RS-2010

Hey guys! This fisher has been under my workbench for about 3 years now, & I know that she doesn't deserve that. So I'm going to fix her c: Last time she played, after about 30 minutes, it would have distortion in the left channel. I'd imagine that's is one of the caps that is doing that. But, when I last worked on it I for some reason disconnected the power supply P.C.B & now Im soldering that back together. I've found a service manual on hifi engine, but it's not exactly right, so I'll have to find another.

Those Darlington Power Packs in one of your picture don't seem to be the right ones. Were they replaced? Manual shows they should be STK0105 (100 W Quasi Complementary). The ones you have in there look like they are STK0080. (80W full Complimentary)
 
Idk it appears that it was worked on before I got it, because some of the wires were soldered, & not wrapped tightly like it comes from the factory so they might have been replaced.
