I did not read continuity across any of the 3 connections on the power switch when I turned the radio on. Does that mean the switch is bad or very dirty? I've deoxited it several times.

Well, why don't you simply put your ohmmeter across the switch ans this will be your answer?

Can I put a jumper across 2 of the pins on the power switch to see if I get power to the radio? If so, which 2 do I jump?
Can the switch be repaired? I dont dont have a spare one.

Are you implying you do not have a digital multimeter or cannot measure ohms in any common way?

The switch is likely OK as 117 tube, according to you, glowed and went out. Which is normal. Also 117 is not part of the filament string, it is directly connects to the AC across that switch.

I consider it extremely awkward borderline impossible to troubleshoot things without a multimeter. If you do not own one, a cheap chinese one on Amazon is on an order of $20. I seriously suggest you get one, if you do not have it.

I do have a multimeter. When I measured across the switch pins I got no continuity. I thought the switch was bad till the 117z3 tube glowed when I last turned it on. I may have gotten bad connection with my mm probes. I measured again and got 21 ohms with the switch off. Open with the switch in the on position.
I also got voltages at some of the test points but not correct ones. The guide indicates switch 100 and 101 or the 117z3 tube from my readings.
I dont know the pin number system of the ac/battery switch.

Could that be that your On/OFF positions are switched? Not sure how it is possible, as it is part of the potentiometer.
Yes you could short it, but I would try to take a good look at the pot, possibly open it (with most it is not a big deal).
