A 2D21 or a 1D21 ? The 2D21 is a heated filament thyratron, which would work, and will have a more behaved flash rate. But the 1D21, which is a neon strobe tube will have a more dramatic effect. Its not intended to drive a dekatron, but the pulse is more than adequate to pulse a dekatron directly. Or are you just using the 1D21 to flash ? I made a ruby laser flash circuit many years (decades) ago. It had a LRC network for dumping charge into the flash tubes. They had to be carefully calculated, or else the flash tubes would explode. That wasn't as dangerous as it sounds. The tubes,and rod, were enclosed in a dual elliptical aluminum housing, that would catch the glass (quartz ?). Down side, is that, that housing would get all scratched up. The rod not so much. That seems to P.O. the bosses. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group. To post to this group, send an email to [email protected].
