Hi all-
I am using a 50mA PS for the HV piece. Anyways, everything is working
great but I notice what I would describe as a kind of light haze around
the digits. The digit itself doesn't look like it is flickering but the
haze looks like it is. I've tried two out of the 6 nixies so far (these
are IN-14s) with the same results. I'm just wondering if anyone has
seen this before and if it is anything to worry about.
Thanks,
Dylan
Dylan,
That is normal for most Nixie tubes, except the early styles. The haze
is caused by the mercury in the tube, which was placed in there to make
the cathodes last a long long time. Ionized mercury is violet, among
other colors.
