The front face gets disassembled, washed and the the rotten foam gets replaced...
Here we have a shot of the outputs. Genuine, brand-new ON Semi output transistors. These are superior to the original transistors... tougher, better frequency handling.
The old transistors were soldered into the sockets. Can you believe that? There is only one way to get the trasistors from the socket...
rip it out.
It destroys the tansistor and the socket by pulling the contacts or posts out of the socket or the transistor.

luckly, I have a bunch of NOS TO-3 sockets. Half the transistors were shorted anyway (left channel), so not too much lost here. It took about two hours of work to replace the sockets.
You can see where the crimped contact pulled through the PCB.


AAAHHHH!!!! I just shook my head the whole time I worked on these.
