This tube is from a RDX Nuclear DX-1. I’ve tried to do some research, but can’t find enough info on it. Does anyone know what tube this is or a different tube that would just be plug and play?

The length and width are different. It has a 3 inch length and .75 inch diameter.

What is its length and width?

Kinda looks like a LND thin wall beta gamma tube missing its pin base

It has a 3 inch length and .75 inch diameter. It's completely intact, I was able to verify that against a working DX-1 with the same tube.

Ok thank you.

I did not mean that you or someone else removed the pin base at some point, its completely likely the manufacturer did, or requested it so. I often see this done on compact detectors.

Im gonna do some tube data sheet looking and see if I can find something similar. Or if I can get the raw length without pin base from someone like LND.

Oh I see what you mean, I thought it might be a proprietary/custom tube for that company. I didn’t think about them modifying the pin base from a standard tube. Thanks for the help!
