Hi All,
flash tubes do not break down at the 200-400V that the discharge cap
is rated at. There is a small pulse transformer (8-12kV) that gives them a
pulse to ionize the xenon. You can make cool plasma sphere's with the pulse
transformers...
If you run them off twice their rated input voltage and oil bath them using 2
in a push - pull configuration with SCRs.
