the two rates are the vert and horz (30 and 7865) these are for setting up the scope sweep speed.

I am looking at a factory manual, the scope readings do not match up, with the sams so can't really help. So you are back to checking for a pulse (should be two a vert rate pulse and a horz rate pulse both are for blanking.

you can trace the pulse from the flyback (should be pretty big at the horz rate, like 200v pp) thru a cap (.0047) thru the resistor (33k) thru the diode all the way to the transistor, and then see it at the emitter.

The best way to know for sure is to have a working set to compare to, but I realize that is not something that you have.

I would check the diode (easy since its already been clipped), and the transistor (again easy since it's socketed). if they check use the scope and see if you get both horz and vert blanking.
