Removed the multi-tap power resistor and subbed in some replacements and bingo! We got a raster and a little sound. The picture was dim and the sounds was very low, mostly the occasional scratch. The picture got dimmer after a few minutes of operation. Still, progress! We now know we have something to work with. And it was cool to see the little dot in the center of the screen when we shut it off, haven't seen that in years!
The power resistor had no visible corrosion. I may smash it to see the insides, I am still surprised that it had drifted so far off.
Working on a parts list, digging through my stash to see what I have on hand. The 21FAP4 arrived intact and in the original box with the pin protector. It is supposed to be NOS and it looks like it. Once I get the set working properly we'll give that a test.
Bob, after watching more of your videos, I am leaning towards replacing all the resistors and couplates like you did. What do you thing of replacing the sockets out of hand? After watching the trouble they gave you I am quite tempted to do so.
As to the couplates, I was hoping I could ask you for part numbers for the components. In return, I would take detailed construction pictures and post them in a separate thread for easy location for others in the future.
Thanks for all the help folks!

Reason: Wrong CRT number. DUH!
