I think this may have been my own fault, I think I was running it without the IV2 focus rectifier in the set, I had probably pulled it months ago testing out another set. Could this have damaged anything?
No. If this is the only fault, the set will operating again when you replace the 1V2.
But you reported some kind of arcing. This seems to be a more serious problem.
