"A quick plasma globe test"... thank you for stating that. I recently purchased some tubes but have not put them in circuit, and was unsure, but the "plasma globe test" is a great idea. My purchases were ok. At least they were not gasless, I should say. On Tuesday, February 21, 2023 at

I think it was only Ericsson that used that B26A base on nixies? Jon. On Wednesday, February 22, 2023 at 4:37:23 AM UTC Nicholas Stock wrote: > Looks very much like that Ericsson lab sample Jens. What voltage did you > test yours at? A quick plasma globe test didn't show any gas ionization, so

> or it wasnt a functional sample It appears that there is cathode sputtering on the glass so it probably was functional at some point. You should see if the glass is crumbly around any of the pins. On Wed, Feb 22, 2023, 12:57 AM Audrey wrote: > Very very interesting tube ❤️ > > On Wed, Feb

My apologies, I honestly don't remember the ignition voltage, I got this tube back in 2009 I believe. I seem to vaguely recall that I needed a rather high voltage, and in some of the photos you can see that parts of the bottom wires light up as well, so there are definitely some issues with

Looks very much like that Ericsson lab sample Jens. What voltage did you test yours at? A quick plasma globe test didn't show any gas ionization, so I fear it has leaked at some point (or wasn't a functional sample...). On Tue, Feb 21, 2023 at 8:25 PM jb-electronics wrote: > Neatm looks like an

Neatm looks like an Ericsson lab sample: http://www.jb-electronics.de/html/elektronik/nixies/n_rd125.htm . Where did it come from? Jens On 2023-02-21 10:58 p.m., Nicholas Stock wrote: Any ideas? No gas by the looks of it though Sent from my iPhone -- You received this message

I have come in late on this. Martin will be right. It does look similar to the Hamamatsu thingo. I was going to suggest it is a flash tube for the StroboTac or similar. [but that should glow I suppose]. I love doing "whatsits". John K -Original Message- From:

Very interesting! Are the internal pins (not the "C" shapes) coated in glass? If yes then the tube probably contains gas. If not, then it might be vacuum. Where did you find it? Maybe that can help us figure it out? Cheers Jens On 2019-04-09 9:25 p.m., Nicholas Stock wrote: Anyone have an
