At its age, carbon comp resistors will have drifted. Up in value unless
IRC which weren't carbon composition resistors anyway. And the oiled
paper capacitors were leaky when new, worse now. And a mica or two,
especially the molded postage stamp variety can be leaky, plus there are
probably some papers molded to look like micas.

Jerry,
The other thing I need to look out for is a slipped disc in my back! I'd
forgotten just how heavy these old radios are. I had to enlist the help
of my XYL just to slide it out of its cabinet!
It's had the Power Supply electolytics replaced, and a few other Rs and
Cs, but otherwise looks totally original. The case needs some TLC, but
the front panel is very good. Picture here:

Watch out for electrolytics in odd places, like maybe a bias supply
