I was watching this set, and the horiz went out again. It's strange how some sets just work, and others like this one frequently have components going bad. Compare this to the other 2 early 60s b/w Zeniths I have, the other two (that 23" console, and the 19" metal tabletop) had a much harder life, were stored outside for some time, the 19" was used so much the crt is a bit on the weak side. This set spent most of it's life sitting in it's original box, I can tell it was hardly ever used because the crt is so strong (I set the brightness nearly in the middle) , but I keep having to change resistors out of it. Changed nearly every resistor and capacitor (even some ceramics) in the horiz circuit. Whereas that 19" table top worked when I got it, and I just did a recap because I planned on using it alot. Never had a single component go bad on that set. The 23" had the usual leaky paper caps, and a few bad resistors, but worked good ever since I fixed it initially. But this one frequently needs repairs, I would just stop using it so much, but with space command and all it really is one of the sets I like best out of my collection, and it makes an excellent picture when it does work...

The problem turned out to be the 1meg resistor I circled in red in the schematic down below. It didn't actually test bad, but I found by shaking it around and heating it up while the set was on, that it was the source of my problems.
