The only component not replaced is a large-ish mica cap buried under the LO coil assembly. I will get to that in a day or two after gently lifting the coil assembly.

The two original paper caps in the LO compartment are the ones that you say are still there and need to be replaced?

Don, here's a photo of the underside in its as-found state. Not too bad but not something a sane person would plug in and turn on without at least replacing the electrolytics. Obviously it had seen some repairs over the years. I have since replaced most resistors and capacitors and replaced the old 2-wire power cord with a modern 3-wire.
