    Hello,
    Im working on a nixie clock project and had a question about the power supply.
    My DC-DC converter is 11-12Vin, 180V@12mA out. The tubes im using are IN-14's, which require 170V at 2.5mA, datasheets here and here.

    Im not sure what the best way to limit the current to these would be, and i really dont want to just experiment wit resistors, i tried it once and fried all my ic's (http://forum.allaboutcircuits.com/showthread.php?t=48459&page=1).

    I just replied to your other thread regarding how to measure the Nixie current.
