Hey experts!

Been tinkering with my arcade for a couple of years and got it to a decent (for me) state. I now want to fix any of the annoying things left that I can fix. Been reading up tons but clearly need some help adjusting my CRT and/or the Wei-ya 2628HR chassis. I've been pondering everything from adjusting the convergence rings (oh no!) to adding convergence strips to just messing with the red drive 😊

So, three separate (small) annoyances I'd like to fix

1) The edges have a weird pincussion-like effect. I "solve" it by stretching the image beyond the screen but I'd like to solve it. You can see it clearly here and to a lesser extent on the pattern

2) I think this is recent. Tiny white dot patterns scan across the screen really fast. This happens all the time continuously

3) Colour bleed. This only happens with some games. Even with a pandora box some games are fine, others have excessive colour bleeding across all colours while some mainly get it with red. Pacman gets it worse

and here's a couple where there's no bleed:

Would love any suggestions on things to try for each of these!

Thanks!
