Yes it has came up before on the power switch/tone control. They can be hard to find. Go to philcoradio.com at bottom of page and under resources look up Mark Oppat. He sells many type of old radio switches.
 That is a transformerless radio . Be warned that the chassis can be energized based on the way you have plug in outlet.
If you run the radio without a speaker for a load you could do damage to the rectifier tube.

Thanks Mike
I may have dealt with Mark years ago.
I have a "light" current limiting jig and I also connect any of this vintage stuff through a B&K isolation supply.
I was reluctant to use the speaker it came with because it is a atwater kent speaker added to it that appears to be in poor condition, also I don't know if it's a good match, though it seems to have been there for a long time.


I will trace out the wires on the chassis and reconnect the speaker removing the damaged wiring.

One wire is darker in color than the other 3 I assume one of the wires to run the field coil...but will have to check.
I suspect the load is somewhere between 1to 5k

How much voltage is used to drive that speaker field coil?

Thanks for the help.
