Regarding the horizontal ringing, after shunting the crt control grid to ground to confirm the issue was not in the video, I replaced the 56pf capacitor in the yoke and while the black bars didn't completely disappear, they seemed to be less noticeable. Is it possible the cause can be coming from more than one place?

I also replaced the 6SN7 in the vertical oscillator and the vertical collapse didn't return after that. I'm going to keep an eye on it though as it went away and returned before.
