I also wouldn't doubt, the CRT is acting funky.
When I replaced the flyback in the clones, I always replaced the focus rectifier stick.

i dont have a schematic but i think the focus rectifier is a 66 meg 6000 volt and i know the hv rec is good but i will try another and the reg tube does do alot of hissing or crackling but no arcing or corona smell.
