The weird problem with this tv was the socket for the 9AU7 horiz osc tube. One of the pins for one of the filaments was not making contact, and all the current was flowing just through 1 of the 2 filaments in the tube, so after I started the set up a few times, that one side of the 9AU7 would burn out. I burned out 2 new 9AU7s before I figured this out. I bent the contacts in the socket back in a way that it worked (only after burning out another 9AU7 testing it out). But tonight I turned it on and the same problem reoccured and took out my 4th 9AU7. This time I kind of screwed up the socket worse trying to bend it again so it would make a tighter fit. I finally jammed a bit of wire in the socket along with the pin of the tube not making contact to make a tighter fit, and this seems to work. But I'd like to come up with a better solution? But for now I'm not moving that tube until I get more, it being my last 9AU7.

Pic shows my messy looking sweep board where I had to replace one of those "component combination" units.
