7.9mm numeric tube manufactured by National Electronics
The NL-7009 is a clear glass miniature numeric tube manufactured by National Electronics. With its 7.9mm digit height, it is the smallest tube made by National Electronics, and one of the smallest nixie at all. Due its small size it would be perfect for projects where space is limited (e.g. Wristwatch), but the tube is not that easy to find.
