"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.

I think it was only Ericsson that used that B26A base on nixies?

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.

the bottom wires light up as well, so there are definitely some issues

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".

Anyone have an idea what this is? 4 pins. Doesn’t glow next to a plasma globe 
and doesn’t have any distinguishing markings on the base except some hand 
written numbers.Appears to have two C shaped wires connected to each pair 
of pins with a small gap between the electrodes.

Re: [neonixie-l] Mystery tube

Looks like a spark gap or TR switch, but I suppose it could be a nitrogen laser.

Re: [neonixie-l] Mystery tube

be vacuum.


Where did you find it? Maybe that can help us figure it out?
