Philco 21 repair
#34

The resistance is right on the money so you're good there.
I would have no problem w/leaving the cap across the choke out.
The simple answer to the line voltage question is to measure the 2.5v heater voltage and use that as a guide the to determine the proper line voltage. If it's say 2.7v then maybe but if it's 3v or higher then use a variac to adjust the line to 2.5v and see what the line voltage is. Then if you like you can use a bucking transformer to drop the line down a bit.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
