I see some spider chips on the board.

Full sized schematic of the board is here:

Service manual is here:

Maybe try Steve Kulpa?

Here's some information for board repair people:

It appears the transistors which are "house marked" as 224N1 are actually 2N3904 and the ones marked 223P1 are actually 2N3906.

Unless there is something wrong with the spider chips, this board should be a fairly straightforward one to repair.

There are some forum members here that do board repairs.

That's more like it.

It's good that you are mounting the heat generating parts higher off the board for better air flow. Also good that you use sockets for the integrated circuits.

Good job spotting that blown chip.

Thank goodness the schematic calls out the real part numbers instead of "house" numbers. A nice upgrade to the sound would be to replace that silly volume switch and it's associated three 1.8k resistors with a normal 5K potentiometer to control the volume.
