I think people have posted before that the version B & C of those tubes are darkened
with a coating to help contain some of the x-rays they can produce.
With 14KV and the reg tube removed, that means its caused somewhere else. Be sure
the HV rectifier is good. Then check for the Possibility of problems in the horiz output
drive, or in the flyback. With good width is may be in the flyback.
A good place to start is the voltages around the H output tube. Also be sure to check that
the flyback is not getting too hot while on, check bias voltage on H output, and cathode
current.... I think a number of people here have been on that street before.....
