Let's see, if there is no audio at all, including no hum coming from the speaker, then there may be no B+ voltage going through the set. Find a schematic and check for the B+ voltage in various spots starting from the cathode/filament of the rectifier tube, the filed coil of the speaker, and the plate and screen of the power output tube.
Regards
