Ok, that makes more sense. So in that case High Vacuum is required to
evacuate then.
What sort of pump would I need to be looking for to achieve that?

That is also the purpose of using a getter too right? Remove the majority
of the gaseous impurities before back filling with neon/penning gas mixture?

OK, that's once the tube is pressurized with the desired gas. However, to
cleanse the tube of impurities, it must be baked-out and evacuated to a
rather high vacuum. Even at a high vacuum of 1 micron, there are still an
extraordinary number of gas molecules present, on the order of 10^16 per
Good job.
I make similar projects for Price stats.

I think you mean 10-50 microns (which is 1000 timer lower), not 10-50 Torr.
One atmosphere of pressure is 760 Torr (760mm Hg).
I've seen neon-sign texts stating the need to get below 1 micron for proper
bombarding, and I imagine nixie tubes are similar.

Nice that you got it running and thanks for reminding us all of the
breakdowns of capacitors, happens to often and a lot of people never
suspect them.
I nice forum that has helped me to repair stuff on a few occasions is:
https://www.badcaps.net/forum/, lots of helpful people there and
Look at Dalibor's videos.

You
Just a quick addition - the dead Xicon electrolytic had no visible signs of
failure - no bulging or leakage at all. The DMMs, however good they are,
were mostly useless in this case as they were simply confused by what was
happening - no DMM or analog VM would have helped much - an analog VM
So,
I have had an original NixiSat from new, so a long time now - I detailed
it's restoration to a more modern time source and working condition in
these two threads:

Good day.
Since we require to reach vacuums of 10 - 50 torr depending on the gas
mixture. What sort of vacuum pumps are we looking at sourcing to achieve
those levels?
