Alright, my nixie tubes are rated for 2.5 mA max, and 170V max, and I have a 180V supply.
When I tried to current limit them nothing works.
I tried a 100K pot, but by the time I got it down to 6ma, I had lost too much voltage, and when I tried the calculator in here http://www.mcamafia.de/nixie/ncp_en/ncp.htm
I get 10K (160V, 2mA) , but I try this, and the whole thing just lights up in a ball of plasma, so theres obviously something wrong.
If it's worth anything, I'm pulling the cathodes to ground through a transistor.
So, help?
