Hi Mike,
If you open the can, there are likely no indications of value. Hopefully the schematic is marked. Since these are "bypass" capacitors, the values may not be important may be able to just pick the highest value in the can and use for all. Personally, I think that this stuff is simpler than transmitters and UHF stuff.
Re the coils, I would be starting out just verifying continuity as a "Go - No Go" t, test. Later on, if there are issues, then concern yourself with whether the resistance is correct. I would do the first few steps of the "procedure" that I posted prior to stuffing the caps, to discover other "deal breakers" before getting too deep into it.
BTW, I did leave out 2 things:

BTW, I did leave out 2 things:
- Add an in line fuse holder with a 1 Amp fast fuse.
- To protect the power transformer from shorts if the filament in the 80 breaks, I place 3A 100PIV rectifier diodes in series between the HV secondary and the 80 plate connection. Anode to transformer, cathode to 80 plate. This will protect the transformer in case of a short.
