John, I happen to have a few of the NHK GD412-200V spark gap tubes. I accidentally thought they were neon bulbs and installed them on the Wemos Nixie Clock kit from Ian at Nixieclock.biz (a great kit btw.)
What voltage is needed to cause them to glow? Since these are 200v spark gaps, I am assuming a voltage over 200, but and curious what you used. Did you ever use them for a project? - Bill On Thursday, December 19, 2019 at 1:07:28 PM UTC-5, jrehwin wrote: > > Mouser.com or allied.com. Their new number is A9A.
