battery pack for Philco 39-85 121
#3

I agree with codefox. It is a bad idea to power up old electronics without looking at the insides.
The first tube radio that I got had been mickey mouse's party penthouse several years back; its sometimes surprising.

The old capacitors are likely not as good as they were 70 years ago. Some might be completely broken. I am uncertain for that specific model, but the wiring of some Philco from that era has become brittle and might need to be changed.

Your specific radio isn't that complex, you might want to look at it, change the capacitors first. Just today I heard sound from a battery-operated radio that wasn't working prior to my changing 8 capacitors and making a battery pack similar to yours.

Hope you like your radio.
Once you make it working, you'll be happy to have made the time investment into it.!!
