Do you have the yoke in circuit? I don't see if you've mentioned if you have 330v on pin 10 of the CRT socket? 330v is the B Boost generated by the damper, and if it's not present or low could explain low HV. B Boost would also be measurable at pin 8(cathode) of the damper. Otherwise a weak 1B3 HV rectifier or drifted high R187 HV filament resistor could explain it.
