I got the set up on the workbench today. Looks like serial # is X4136. I wonder how many were made ?
 Super clean inside the HV cage. Interesting focus and centering magnet assembly. It is both a permanent and electromagnet.  I pulled the 5U4 rectifier and tried a power up. I quickly discovered a blown fuse and replaced it.  Success! Unloaded HV secondary is around 750 VAC.  Encouraged, I decided to give it a brief try with the rectifier in while carefully monitoring the B+. Things looked good but after a coule power cycles, the 5U4 died. I then worked on the frozen tuner a while and was able to free it up. I popped in a new 5U4 and gave it another go. It held up and I was able to pick up some FM stations  I also removed the weak CRT and installed a 8XP4 bench CRT. I have to keep it at an awkward angle because the grounding strap makes contact with the HV button. No luck - 0 HV. Still not bad for a first power up. I'll get to recapping next.
