First off IIRC C1 is a 105 deg C & the others are 85 deg C.
Look at the old C1. If you use a lower rated cap it will NOT last
long. The new C1 probably got stressed out when wired wrong &
is the cause of your ripple.
After the ripple is fixed next step is the vert so if you are ordering parts
you may want to order the vert tube. Should be cheap as its
pretty useless for other apps.

C1 has already been swapped out for a new one, but I'll double check the temp rating on the one I used.

I also tried swapping in the vertical tube, no luck there.

I still have not replaced C3, and considering my HV is low and I'm still hearing sparking from around the horizontal section, I'm not sure my problem is originating directly in the vertical section.

I'm going to replace C3 over the next few days and see what changes. Worst case, C3 needs to be replaced anyway. I wonder if that didn't get damaged.

Okay, finally had some time to sit down and work on this.

C3 is replaced. I didn't notice any change in the vertical behavior, but I hooked up a source and it looks like the waviness is gone.

I've ordered a new C1. It turns out that the C1 I swapped in is a lower temperature rating than it expected, so I've sourced another and will see if that helps. Not sure it will, but maybe it will at least get rid of the buzzing that's come up.

I made another video to show where I am. https://youtu.be/gIrCuJHy9OQ

Any thoughts on what I should check next?

Does fine tuning help, or is that the best you can get the video? Are you on the correct channel?
