Resolution lines on Zenith roundie

[Yamamaya42]

I may very well have the exact same problem on my CTC-16XL, have always been seeing the same annoying lines at the top and not been able to get rid of them fully.

Have looked and looked at horz blanking area and not found nothing, not really knowing that the vert blanking was tied as mentioned, to the plate of video output, in my case they are a .01 cap and 2 res, 100k & 68k, and have not been looked at very closely yet, i'm in no big hurry to yank it out and check, cause its just an annoyance at this point.
