Default Jitter on locked horizontal part of image - B&W transistorized TECmonitor

I have an older monitor from a video game - and it has a jitter on the
horizontal lines on the screen (vertical is locked), yet I don't see
this jitter on the H Sync. Using a signal generator (Cross-Hatch, Dot,
etc.) and all outputs are the same. Game source also shows same jitter
on same screen.

It is not the WICO monitor signal generator as other B&W monitors show a
locked image.

Schematics he

Monitor has been recapped. Horizontal does lock, but jitter still present.

Suggestions appreciated!

Thanks,

John :-#)#
