Repairing old 1951 sentinel 424

[Patnukem]

Of course when I start figuring one thing out something else happens. It still needs a couple of small adjustments but it looks fine for now I did run it a long time today and noticed the Flyback seems to be getting to hot and could see a little bit of bubbling on the corona dope I put on. Is this from the excess B+ and or from running it so long today while I made adjustments I would like If it would be ok to use for 30 minutes at a time a few times a month. anyway here is a photo and video the horizontal has a bit of a roll over on the left (the drive was helping but now its turned up all the way) and I probably could tweak the vertical to adjust the shape a bit but It is a million times better then before!

EDIT:
I fiddled with the controls a bit more and was satisfied enough to put it back in the cabinet! I think the Flyback overheating was caused by it being on so long with the slightly higher b+ and it being in the upper 80's today. The garage I was working in was probably 90 or so! I had not heard or seen any more little bubbles or signs of the Flyback overheating since toward the end of that long adjustment session!
