Can you help me identify some tubes please?

[kay486]

Hi there, i just came across these two devices with nixies. Some guy sells them at a local auction site.
So heres the thing, can somebody help me out with identifying the tubes? Or atleast the size? I can tell for sure without a proper scale.

Thanks

Hi,

looks like German ZM1080 or Z570M Nixie tubes to me.

You're not giving us much to go on. They are probably NL8xx series, but it's
hard to tell exactly without seeing the tubes or the bases.

The size is definitely the same as a 12AX7, at least in the one with the open
cover. For a scale, see the DIP pin footprint an inch away from the tubes.
That's 0.100" per pin.

Thanks for the fast replies! I though it would be some 15mm digit tubes, i just wanted to make sure.

Well, you can guess they are soldered onto the pcb, this rules out NL-,
CK-, or ZM1030, and they are not large tubes (estimated by the
nipple-to-radius-ratio), so there is not much left :-)
