The usual culprits for a non-functioning tube type radio are the vibrator and the 0Z4 rectifier tube. These are both metal cans and located on the left side of the sub assembly with the speaker. The vibrator is the larger one and you should hear a hum from it when the radio is turned on.

Solid state replacements are available for both of these components (no hum from a solid state vibrator) The radio in my 49 Custom has been working fine for many years with a solid state vibrator. No experience with the 0Z4 replacement.
