My Christmas day 9T246 restoration! Almost.....

That's looking pretty good. There's a good chance that replacing the rest of the caps will help the sync lock in better, then make the horizontal waveform adjustments as Dave mentions.

Yup. And make sure you replace the molded paper caps along with all the tubulars and electrolytics.

I would also replace the silver micas in the horizontal sweep section, as those seem to be failing nowadays.

Then, check the tubes and high value resistors, and tweak the set with a Test Pattern.
