Dirty pins?
Did you wait for the tube to warm up before measuring the voltage?
If the voltage stays 430V (429V, no different) WITH the tube in, then either the tube is bad, or the socket is dirty, or the Cathode is not grounded.
Judging by it working briefly, my bet is on the dirty socket. Or loose pin.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
