Strange IN-18

[Adam Piórko]

Hi,

To start, I do not own the nixie tubes shown in the photo. I came across an image featuring a tall version of the IN-18. Is it really an IN-18 (on the right)?

BR,

My guess would be NO because of the excessive height, compared to the one on the left. All tubes I've ever seen or worked with have a set of physical specifications, with tolerances, as well as electrical.

Ira.

Could be a prototype. I have 2 tubes presented by different sellers as IN-12 prototypes and they also have a fine grid and are larger. I believe someone on this group has one of these IN-18.

The right tube appears to have digits bent from wire? Very interesting.

This is 100% not IN-18.

One of each of these tubes has just been listed on eBay. Please someone buy them so I cannot.
