You might be surprised - It may work right away. Or it may work but hum loudly. The capacitors in those old radios tend to be bad after so long in storage but you can replace them pretty cheaply.

Sometimes the electrical cord is frayed or insulation brittle and cracked. If that's the case, replace the cord before plugging it in. Again, that's an inexpensive repair.

Often times the tubes still work. If one is weak or not working at all, you can still get replacements. I have a ton of tubes, so I may have what you need, if you need any at all.

Write back and let me know the condition. If it isn't working, you can probably get it running again pretty easily.
