Trouble firing up my new HeNe tube

[Ghostchrome]

I did. I left positive because I couldn't in good faith leave negative for something that was advertised as as-is untested. I did note the tube was EOL aka dead. Oh well I'm going to keep it around to use as a demo tube so don't have to keep handling one of my good tubes to show people.

Yeah, it is a cool looking little tube. I'm going to keep mine around too.

On a related note I got my PSU in the mail today. I'm going to try it with the little 6" tube that I got from Sam. I may have to take wannaburn up on his offer if the tubes he has are similar to the dead one for visible plasma.

Nice. Let us have a look if and when you go for it.
