Thank you, Eric, Threeneurons. What I am taking away from this is: * Keep my thyratrons for the reason I bought them: spares for my Geiger counters. (I have two: because the original wasn't working, the Ebay vendor sent not the parts (missing GM tubes) I asked for, but a whole unit.) *

The Russians regularely used thyratrons, both cold cathode types and those with a heater to drive Dekatrons. What types do you have? /Martin On Wednesday, 2 October 2013 07:29:49 UTC+2, Smiffy wrote: Has anyone done/seen Dekatrons used in conjunction with thyratrons? I just happen to have

Depends if you just want to use one to step a dekatron, or need it between dekatrons, so the second one steps, per every revolution of the prior one. The interstage one could be a problem. That one would need to respond to the output of one dekatron, and then boost it to step the second. The
