Hi Martin, Yes I have heard that a lot of the argon Russian dekatrons have leaks. I am trying to get a tester asap so I can test the ones I have already bought. Probably thought I could just make a circuit quicker myself but time is a rare commodity here.
Thanks for your thoughts. What frequency do you think the link above is putting out to drive the HV ?
