Problem is SOLVED and I may be a complete idiot ! MORZH - I went away over the weekend with my family and kept thinking about this freakin radio the entire time. Amongst other things - you mentioned: "The resistor in the middle is an NTC thermistor, it starts at about 1K and drops to 100 Ohm as it heats up". I retraced all the caps I installed and checked all the wiring. In my first restoration of this same radio, I noticed that I left the thermistor (see picture) in place because, at the time, I didn't know what it was and didn't want to mess with it. In this most recent restoration, due to me misreading the "chassis - bottom view", I wrongly thought it was a capacitor and replaced it with a .1uf CAP. I thought the thermistor was just a weird looking capacitor. When I got back from my trip, I re lookeded at the chassis diagram and realized what I had done. I soldered out the cap and put back in the thermistor - and VOILA - it popped to life - the tubes, the bulb. So in the end, there was nothing wrong with the on/off switch. I hooked up the speaker and the antenna and already it can pick up some am stations but I will still have to align it. You really nailed the problem - so THANK YOU for your help. Also, thanks to BrendaAnnD for jumping in with your help as well.
