philco model pt-4
#2

Hi and welcome,
Can't  leave the circuit open. If you your use a jumper in it's place you'll have a lot of hum. Replace it with a 500 ohm 2w resistor and increase the value 30-2382 to 47mfd@160vdc. This will satisfy the electrical needs but may not provide any magnetism which the speaker requires.

When my pals were reading comic books
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!
