Try a 6U10 if you havnt yet. There is a sleeve on the H hold
pull off & recenter into range.
Focus div just a pair of very high meg resistors, new p## is 800-616.
Dont see that doing it. Burns or bad focus.
Filter cans went but a PIA to get to. Need one of those 2 foot xcelite
drivers to pull chassis.Only good test for FBT is totally unload
it & ring it. If it has shorted turns usually you can also see distorted waveforms.
Other poss is one of the high ohm resistors has drifted up. Gotta
unhook one end to be sure, time consuming....
