For those wondering what the heck a "Beam-X" tube is, here's a rundown on the family. Otherwise known as trochotrons--a counting device, primarily--used to drive Nixies.

Any relation to dekatron? Sounds like a similar purpose, but a different implementation.

Very similar--much faster (to 2 MHz) with no display, which is why they're usually tied to Nixies for that purpose. I think that gas-filled dekatrons have an upper limit in the tens of KHz or less.

We normally think of counters being solid-state and running at hundreds of MHz or more, but back in the day, a counter made from conventional vacuum tubes used a lot of components just to get to MHz speeds. Dekatrons and trochotrons considerably simplified counter design at the expense of speed.

One in the pictures is sold (outside VCFed), so the other one is still available, will take fresh pictures if there is interest.

Hello, I recently picked up a Reuters stockmaster which was badly damaged in shipping. Amongst the casualties is a BX 2013 tube. I'm hoping I can substitute yours for it but at 10€ I'm willing to take that risk.
Looking forward to hearing back from you.
