Yes, it would be worth finding another Capehart changer for parts - even with the bad cloth front panel, these 212 sets are not found that often.
Sorry, try electrolytic capacitors. Mouser Electronics, Bob's Antique Radios, Radio Daze, Just Radios are a few of the vendors selling these.
The 212 is 82 years old now - the capacitors are going to be bad and will all require replacement. No sense wasting your time on testing them.
Oh, and there are two versions of the 112/212 chassis. The early version has two 45 audio output tubes (very pricey) and will use no electrolytic capacitors; its filter capacitors are embedded in a large can mounted on top of the chassis, filled with a black wax-like material, very hard and with a high melting point. The later version uses two 47 audio output tubes and does have two copper Mershon electrolytic capacitors along with a much smaller metal can with a few paper capacitors inside.
If no power has been applied to the set in a long time, there should be no danger of a shock from a charged capacitor, but safety first - if it is the later version with electrolytics, you can use a screwdriver blade to short the positive ends to chassis ground just to be sure. (Never, ever do any service work under the chassis without making sure the set is unplugged first!)
