My approach is to check out the electronics and see if there is anything that may prevent the radio from functioning properly then check out the cabinet and do cabinet repairs first.

Chassis:
Check all coils for continuity and record their resistance on the schematic. Any coil that is open will have to be rewound or replaced. Test all resistors for value within ten percent. Identify them on your list or the schematic. Identify the electrolytic and paper/wax capacitors and put them on your list. Check condition of the speaker.

Order parts. While the parts are coming get that cabinet work done. Make it beautiful again. Then do the chassis and make your beautiful cabinet sing.
