Hoping to get help with an old Electrohome G07-CB0. I just replaced, the flyback, caps, POTs and bottle caps. After I was all done it was just not bright enough and I had the brightness almost all the way up. I kept hearing something arcing sporadically in the back as it sat and turned on. Also, I think I turned the B+ too high and now it keeps blowing F901 (smaller fuse). Obviously I damaged something with the B+, but what would have been damaged? Getting very close to a LCD swap, but I would like to keep this older CRT if possible, but it is hard to justify spending anymore on this thing.

Appreciate any help/suggestions.
