Hi Atlas, and welcome to the Phorum. What is your level of experience with electronics? We are all very happy to help you out in repairing this heirloom and piece of history.
First off, don't even think about powering up this set without doing the following:
Remove the chassis and inspect all wiring. Replace the power cord. It is possible that this chassis is wired with rubber insulated wiring that has deteriorated insulation that is crumbling off the wire. If so, then the deteriorated wiring will have to either be replaced or sleeved. Cross that bridge when we get to it.
At the very least, replace the Power Supply electrolytic filter caps (capacitors) labeled C45, C11A and C11B on the schematic. Don't just "bridge" these caps, replace them. However, it is common (and extremely wise) practice to replace all caps in the radio, as even the non-electrolytic caps fail, either drying out and losing their effect, or shorting which is really bad as a shorted cap can take out expensive, hard to find parts.
The schematic is available here on the Phorum and also from the Nostalgia Air site. I will give you a link to the Nostalgia Air diagram here.

Phorum Experts can guide you to the official Philco schematic on the Phorum better than I can.
Again, keep us all posted; we are glad to help!
