    i had one of those once, the pre-amp went out in it, I just bypassed it on the relay terminals and never looked back. As i recall, there is a single transistor off away from the power transistors that made up the preamp. As for finding a schematic, I haven't seen one in a long time and I'm not sure it was included in the manual, however the manual is available on the Radio Shack website.
