NL-8091's

[Dan Schnur]

I just was given two of these nice large tubes. Both show little signs of use and I was able to test them fully.

Question is, what to do with only two large tubes (with sockets)? Thermometer… Mix with different sizes to make a clock?

I looked online and there are none for sale, so I can’t complete a set of 4 or 6.

Anyone need them?   Know where I can find at least two more?

I am interested.  How much are you asking fpr them?

I have no basis for a price.  Whatever is fair including shipping.

I have a couple I bought a few years ago.  But I'll have to do some research on current prices.  "Fair" is getting into the high range....

If it was me, I'd go ahead and build the clock+thermometer, using a DS3231, which has a built-in thermal sensor. People have made 1-tube clocks, and there's no law against making  a 2-tube clock. As I would say, reading a 2-tube clock is twice as easy as reading a single-tube clock.

When you find 2 more tubes, plug them in and now you have a clock for hours & minutes. Nothing wrong with making the seconds digits smaller, such as with 6091 or 5092 tubes.

BTW, the purplish hue around the orange glow is a sign of excellent health. These tubes should last a long time, so you may as well enjoy them.

+1 for making something with them. I have a design for a 2 tube clock that would work well for them - it would need adapting for the larger tube sizes - unless you just wanted to run wires to them - which is also fine!
I see that you have sockets for them already - so you are half way there!

Two tubes are placed next to each other, with two IN-3 tubes on the left and two on the right. When displaying the hour, the dots on the right light up, and when displaying the minutes, the dots on the left light up. This way, there's no need to guess what is being shown.

I really like the look of 2 tube clocks, and these tubes would certainly make a very nice clock. If you’re looking to sell them, I would say that a fair price is probably around $300 a piece, maybe more, maybe less.
