Greg: So far I haven't seen (and customers haven't reported) our tube to drift with the striking voltage so much that it would not strike. I did some random measurements on old tubes and after few seconds of normal use (clock), all digits strikes at normal voltages. But we gave up on trying to use striking voltage as an indicator - the same tube can differ by few volts in dark/light. The important thing is that it always strikes below 145V.
Cheers!
