Hello Swesterman.

I own one of the bigger brother of your radio, the 47-1230. First thing first you should ensure it is safe to operate your radio. As surprising as it may sound, 60 years old capacitors can be dangerous.

the first piece of advice would be there: http://www.philcoradio.com/tech/plugin.htm

make sure you won't set your house on fire when applying power on the radio.

Then, look for the schematics. It is available online.

An easy test to know if the power and amp section works on such radio is to connect "anything" trough the phono connector - its modern-RCA connector compatible and will accept the input as long as you're set in phono mode (left-most preset button)

Something you will want to consider is to change all paper/wax capacitors from your radio, as they are no longer good.

Hoping this helps.
