The set is starting to act up a bit already, not sure why, not sure if its cause the CRT is on it's last legs, or perhaps that bad 6BK4C damaged something, I swear I saw some smoke, but could not find the source.

But right now, brightness is inconstant, tends to change a lot, but the blue gun is the weakest, AND pin 11 was broken off, and is hanging on by a thread.

So before I do something crazy like try and find a new tube and pay insane shipping charges, OR , work some kind of bodgetastic miracle and fit the 25Vxx22 in this TV from the RCA CTC-90 that I hate! ( only 1.681 inches wider, super glue fixes everything! )

Gonna replace a few more stuff.

X5 with a pair of https://www.mouser.com/ProductDetail/78-BY228-15-TAP in series.
I don't like the look of the selenium rectifier in there now, and it's kinda smelly, so boost may be low or unstable, causing me to turn crt bias up, that will be the first thing replaced.
also, R139,,140,141,142. with new 10kv w1 rated parts.

Not sure if this will help anything at all, as the picture tube is clearly a weak point, and every time it's touched is a risk, but not much I can do, as replacements are so far away,
