It looks like the power supply is about 275 volts DC. The filter cap inside is rated at 475. You will need 6.3 volts AC at 3 amps for the filaments. The Sams is 268-8; I have it if you need it.

The part # is 1328-305 RCA 906128-5011. If you go to his website go to "Radio Parts" then "Transformers" then "Power" Gary always wants you to e-mail him first to make sure it is in stock
