Re: [TCML] Nixie tube at 300 000 volts

Odd that the cathode poisoning increased. The reccomended procedure for that
is to run the tube at an increased current to clear the poisoning. I would
have thought that it might have made it better but not make it worse.

Anyway, glad you tried it and you didn't kill a nixie.
