Larry,
Looks like you've got two more caps in the collector circuit to hot ground.
one is C564(1000p-2kv), should come right off of pin 10 of flyback. The
other one is C569(.39-200v), one end of this cap hooks up to pin 4 of yoke
and the other end hooks up to coil L551, L551 hooks up to jumper JS567 which
goes to hot ground.
Hope this helps!
