After playing with it more and replacing a few more resistors, I figured out not having the yoke/focus magnet assembly effectively shut down the HV. To avoid boring you, I think my spare yoke or focus magnet crapped on me. Next thing I knew, the 5U4 was red. I powered down the variac and swapped it for the original. I got a good healthy arc and some light. After swapping out ion traps and playing with them, I got a decent picture.
I will need to make a rig to hold the CRT while I make adjustments. It's not a good idea to support your 12LP4 on a phone book (flame later, please).
After replacing the caps Chuck suggested and figuring out my spare yoke/focus was bad, I got the horizontal to lock.
The tuner needs some attention and the vertical may. I think the vert lin control may have a bad spot. This set uses a 6AQ5 for vert out, not a good choice.
Thanks for the help and pics will follow here and on my site.
The cabinet has a couple of gouges, which I think stain will hide. Laquor will come later. I really think cleanup and touchup will make this a very presentable set.
