Sylvania Superset Update

I replaced (what I assume is) the boost cap as the old one blew out its bottom and was so far gone one of the leads was broken off on the inside of the cap, I reflowed all the joints on sand around the flyback, I cleaned the inside of the housing. I included a couple before and after photos.

The speaker buzz is still occurring in a slow pulse (approximately 10 seconds of no buzz, 20 seconds of buzz), there were no other visibly bad caps on the board, so I may just replace a bunch in that area of the circuitry.

And while I was cleaning the inside I knocked the convergence & purity rings out of position with my dumb limbs. I ordered an hdmi to RCA converter so I can try to fix my screw up there running test screens off my laptop.

Last thing, I didn't touch the pots on the main board for picture/brightness/color etc, but on the front pots I'm running it with picture & color roughly 2/3 up, and the brightness pot almost all the way off. (I can turn brightness & picture all the way down and still seem an inage, although probably not in a really bright room).

Anyway I just wanted to post this and say thanks again for your help. Overall I'm pleased as punch.
