I just received mine yesterday and it works perfectly. Lights them up like a 
Christmas tree. I can now put my DiscWasher Zerostat "pistol" back in a safe 
place. It's worth a lot more than what I paid for it 35 years ago.

I bought one from a seller in the US (100% positive feedback) for $15.80, free 
shipping. He's sold out but there are plenty of others. Just watch out for the 
ones that are on a slow boat from China.

If all else fails I have an induction coil that's hot enough to generate some 
X-rays.


The "antique" that's been mentioned sounds like the old "violet wand", a quack 
medical device from back when electricity was new and exciting. Today they sell 
tons of them as sex toys. No well-equipped dungeon should be without one.

I carry one of those cheap "ARC" cigarette lighters to test any tubes I
find at hamfests.  And to burn random things (mostly my eyeballs from the
raw UV). because I don't smoke.

  Nixes are scarce at  hamfests, but you do spot the occasional one hiding
in some old piece of test gear or a scrap PCB assembly.

I also use a small plasma globe.   They are only $8 shipped on ebay.  Some even 
cheaper.

I wish I could find nixies at swap meets.  Never have seen them, but I must 
just be at the wrong ones.  I do have a spare globe in my car just in case.

I bought one of these a copuple of years ago.  It seems to me it was a little 
cheaper than this, but not much (maybe $18 or so).  I don't know what the 
original application of these is - I'm certain it wasn't to help a bunch of

[Ice cruncher]

With a single probe. My best guess just an oudin coil

Used often times on argon, krypton and HeNe lasers. If tube lights up it is 
still gas intact otherwise it’s open to air

 But that is a guess
