First Post-Restoration Glitch

Woo Hoo - She's working again. The new vertical output transformer did it. Everything is back the way it was. I had to redo the static convergence as I bumped the crt neck components working on the set but after that, everything looks great again. I must have run the set for about six hours over the course of yesterday and no problems. In some ways I'm afraid to use it much in case something else goes. My wife seems to like the set but is skeptical that it will run for more than a month between repairs.

After more than a year of reliable performance the Zenith is having the same problems as before. I hoped the vertical output transformer I installed last year would last for years, it looks like I might have to replace it again. Any other Zenith roundie owners have this problem with repeated failures? I have not opened the set yet but the symptoms are exactly the same. So far all I have done to this set in the past year is touch up the greyscale. What is it about tube tv sets and vertical problems?
