I found the culprit, R296 was twice its nominal value of 4.3Mohm. Replacing this resistor brought the height back to normal.
After the TV warms up the picture stabilizes mostly, but it is still a little twitchy. Everything was working OK last night, then today I powered up the set and after a few minutes adjusted the vert hold and POOF, the CRT went blank. No bad sound or smoke, and everything else still worked. Any ideas?
