hi guys, I recently bought a bunch of different nixie tubes and as my very first project I designed a simple thermometer with an in-9. at first the problem was that the bar was only about 3 cm long, even at more than the highest rated current. I read somewhere that those tubes sometimes need some sort of "burn in" phase, so i ran them at about 18 mA for half an hour. after that, the bar was about 8 cm long. However, after not running for two days, the bar length dropped again by about 1 cm.
i use a switching power supply at about 130 V. is there some way to get around this problem? or do I have to run them continuously...? thanks! -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
