The NL-934, made by National Electronics of the USA, is one of the largest American nixie tubes. It is a version of the NL7037, but with the addition of a left-hand decimal point. This particular tube is interesting because the top is flatter than the NL7037 tubes that I have, and the decimal point seems to be very much an after-thought.
| Digit size | 50mm |
| Min current | 6mA |
| Max current | 10mA |
Sure would be neat to have one of your single digit clocks that also show the decimal. I have a NIB one of these tubes. The box is almost perfect for it too.
I’m considering making another batch, so feel free to bug me. The clock firmware can show the decimal either in clock mode or digit cycling mode.
