Don't plug it in until the DC power supply filter has been recapped and at least the paper wax capacitors in the audio section have been replaced. Test all coils and transformers with an ohmmeter so you can take early action to replace or repair. Use a "dim bulb" tester to apply initial power to the power transformer with all tubes out. Check AC voltages on the transformer. If all is fine then plug in the rectifier and test the B+. You're looking for smoke while testing. If B+ is where it should be then plug in some tubes and the speaker should be awake.

That's just an outline to get started. We're all here to answer questions. BTW your radio probably has rubber coated wire throughout. Be aware of this and make a plan to remedy this.
