After a few more tweaks, I declared victory on the electronic front and put the RA-102 into its cabinet. I posted an article about the restoration here:

I'll refinish the cabinet when the weather improves.
Thanks to everyone for the generous advice, in this thread and others. Now I can launch the next project -- an Emerson 609 projection TV!
