magnavox 25tr12 c221 no pwr, overheating R504&R524

[Video Doctor]

imworking on a magnavox 25tr12 c221... r504 r524 have 129v on the top
side, and there is 11v running down towards the #2 leg on the flyback(i
think this is B+), leaving a 118v drop across these resistors overheating
them greatly. board is burnt color underneath them. cap432 was bad that
comes off the resistors towards the emitter of q501, I replaced cap. x-q501
seems bad, it burnt the board too and had about .5 to 1vp-p on the base and
about 2vp-p on the collector(if everything was driving it right), and
nothing at the base which runs thru c432. im wondering what is causing such
a high load on the resistors. Is the flyback bad? the flyback passed a
ringer test, but i was reluctant to do a HV dynamic test on it as i still
need the 10x probe that works with our va62a vid analyzer. we dont have a
replacement fly on hand either to try out, so im sort of stuck.

also i am having a hard time finding a replacement part# for the xsistor
q501(atleast i think its q501, but that loc# is actually printed inside out
on the PCB) the x-q501 is labeled
554
-3
m 703
can anybody tell me what a cross reference would be for this part and what
may be the faulty component on this set?

Original cause of problem was C432, goes open and regulator
oscillates, running up to 150~160 Volts. Don't use a
garden-variety replacement cap, or it won't hold up.
Use a top quality, low-esr, 105C part.

These two resistors power the horizontal drive circuit (Q501).
Usually they just get hot and crystallize their solder joints,
and you can clean them up and re-install. It is rare for the
horizontal drive transistor (Q501) to actually short out, but
if it did the resistors would get *very* hot.

Q501 would be 610554-3 by the old Magnavox numbering system.
Use 2SC2482, or something like ECG/NTE 399.
