Thanks, really appreciate the input and suggestions. I'm not trying to keep the amp close to original. Just want it to be working and useful.
Some comments/questions on your suggestions:
1. Why so important to keep the power resistors so close to PCB/power transistors? Will moving them 10" away, with robust conductors, really cause a problem?
2. The 4 output transistors mounted on the chassis (2N3055) don't seem to get very hot, so not sure if I need to move them. (It's the 40410 transistor and the 2 power resistors that seem to be generating most of the heat.)
3. What's the advantage of putting a speed control on vent fan? Maybe just a 120v disc thermostat?
