Back about 20 years ago, I got a bunch (about 30) B-7971 tubes from an
ebay seller who shipped them wrapped in newspaper.
Those papers are very old, they have 1968 dates. I paid around $11
per tube, a few as high as $17 per tube.
I built a 16-tube scrolling array
8.9k would be correct for 180V. You don't need to figure in anything else
for direct drive. If the software/hardware uses PWM to control brightness,
it will still be expecting 8.9k resistors. If the display is actually
multiplexed, that would be different.

I apologize for the title of this post. I changed the body without
updating the subject. I don't see a way to edit it.

Hi - new to this group. Brand new to nixies, and I have introductory
experience with Panaplex displays. I have a direct drive design that uses
current sinks in each cathode connection.
It appears that with the nixie, the anode resistor supplies the current
limiting function. I am using
