Just finished working on one of them! :) I don't have reference numbers but looking at the back of the unit you will see the output STK. Just to the left of it is a PNP transistor, jump the E-C and see if you get your sound back. Sorry I don't have more detailed info right now, but that is as far as I got with it so far.
