@opposablethumb1 here is the schematic.

No sound at all is usually caused by a problem with the pre and main amp. Use your multimeter and follow along the power-in path. Start with the fuse on the transformer as well as your 7V AC line. Make sure that you have continuity on those. Then measure the voltages on your transformer. Remember that the voltages on the transformer are AC, set your meter accordingly. After that check the transistor Qj1~4 on the preamp and the transistors Qe1~14, resistors Re31,32 on the main amp unit. If you have trouble with any of this, post plenty of good images of your boards with your question. That way we can see what you see. Use this guide [guide|21499|commentid=417084] for that
