MUSTS HAVES !
Power supply must be 130 VDC under both zero beam current or max
( full normal brite ) beam current. & varying line voltage. If not suspect
Q801.
Too bright. REPLACE C559 no matter what, its very common on ALL
brands of TV's, Its in the top ten TV problems. Lots of different symptoms too !
G2 must be about @ 300 VDC too high = too bright.
CRT cathodes need to be @100 VDC. Too low too bright & visa versa.
Blows HOT. Be sure its running cool. If not it WILL give up soon.
NOTES : The FBT's in this era of Pannys / Quasars were trouble. Usually
windings shorted & it cooked, crackled, smoked then blew the HOT.
It ended the TV often. On yours it MAY be it has a bad triple / divider
section.
Last keep in mind to do things right you need: a variac / isolation transformer(S). quality meter & good 100 + Mhz scope with 1 KV probes. Anything less is pushing it. Just think of the $ in blown parts you will save
if you do more sets.
