You'd have to unsolder one side of a capacitor to test it ... but which ones?

What you might do, is find out where the local weather station broadcasts from,
or perhaps park by the local airport where you KNOW there is going to be loud
signals, and see if you can hear them at all. Then you know if the radio is
dead, or just deaf.

If you can find a signal, bring a small screwdriver along, and try to tweak the
transformers and variable caps inside for best signal, it may just need a good
alignment.

If the caps are dried out ... you're SOL.
