I was fortunate to have acquired such a set and used its inductors to populate my restored chassis. This was ten years ago and the chassis is still running with those 'pristine' white inductors, and that includes one year of use at the Early Television Museum demonstrating the one successfully rebuilt 15GP22.

I'd have probably dunked those inductors in wax to help preserve them.

Here are more images of what it have to work with.

Now that I'm motivated and thanks to everyone for your great knowledge, advise and encouragement this project has begun. Like a long Wagner opera or I guess in this case the whole Ring Cycle the prelude has just started.
Prelude; Got Sam's and RCA service manuals and will have printed copies for making notes, notes and more notes.
Round up the necessary test and alignment gear best used for the chassis.
Have a CRT holder fabricated to facilitate live work and adjustments (something that looks like what Bunker Bob used when restoring his CT 100s.
Go get lots capacitors this chassis has quite a few
All of the tubes checked good.
ACT 1 Coming soon; Change capacitors and have correct power supply voltages.

This chassis must have seen little use, Not even the wax has started drip off of the capacitors.

It will be interesting to see how age verses usage has effected the capacitors, inductors and resistors.

As pretty as it looks there are so many ugly caps that will have to go.

It is rare to see a HV section this old and no goo

Look forward to Act 2!!!
