Thanks for all of the info, guys! My plan is to leave the coil alone for now. I'll measure it tomorrow and see what readings I get. Given the closeup inspection, I suspect it is fine and only the wax has cracked. I've removed all of the paper caps and made careful notes about their connections. I haven't touched the electrolytic caps in the metal cans yet. Thanks to Codefox for linking the schematics.

Kevin, thanks for the details on the chassis cleaning and removing the tuning glass. I'll give the glass plate another try. I didn't want to pull too hard on it if I was missing another screw or connection point. The white backsheet is quite dirty and I'd like to clean it. Presume it is made of plastic, so it should clean up nicely.

I suppose I should replace all of the resistors as well. Upon closer inspection, the rubber coated wires on the underside of the chassis are mostly dried and cracked. Replacing the resistors and wires looks like it will be a long and tedious task. I think it will be worthwhile, though.
