Hi! I've been using INS-1 nixie lamps for a while and they have always ended up flickering after a while. I think i might be doing a couple of things wrong.
A) Polarity. They light up any which way you wire them. from the Datasheet (link) <http://tubehobby.com/datasheets/ins1.pdf> i can't definitively tell what is the anode and what is the cathode. I know the dot means something, but what it does I don't know. (Picture of INS-1<http://f.cl.ly/items/2g0Z301L1c3f2y1R0n1e/Image%202012-09-29%20at%204.51.03%20PM.png>) I have tried wiring them either way and they still flicker... This is what I think it should be http://f.cl.ly/items/2u1p3x3V263X3e3M0s3o/Image%202012-09-29%20at%205.34.01%20PM.png, is this correct? B) Current. I have a 170 VDC power supply with a 221k Ohm current limiting resistor. It has been been running at 0.55mA. I'm now trying a higher current limiting resistor that brings the current down to 0.45mA. Seems to be working, but I've had ones that worked before and then they start flickering.
