Ahhhh! Dude, that's super helpful! I did find one of the electrolytics near the flyback popped out the bottom as well, I think it's that boost capacitor you mentioned.
Is there any common amperage rating I should aim for? The input according to the SAMS is 120V/900mA, but the voltage going into the degaussing circuitry is 76V or 78V.
I can always measure the current flow through there.
Either way, here's the snippet of that circuitry. I can not believe I read "Degaussing coil" at least 5 times, and didn't put it together.

Thanks again, man. You've been extremely helpful!
