I think the point BB on the flyback is the B+ Boost, this runs all the way up to
the picture tube screen adjustment pots through that resistor... R108 10K
Can you check that one, and be sure it's ok....?
Also can you verify that if the flyback has "BB" stamped on it, that there is a direct
connection to parts like C 113, and those 1.5 meg ohm resistors for the
shunt voltage reg. divider circuit...

there is no BB on the flyback and there is no BB shown on my schematic.

if you are useing an rca schematic the locations are different numbers so the 10k that you speak of i think it comes right off the flyback on a 720v boost source and runs to the focus coil then to the linearity coil then to one of the 1.5 meg resistors at the hv regulator then to the yoke.
