Mystery Tube Time

[Dagwood]

Evening

A friend gave me a few of these today in the vague belief that I may know what they are😕

Even Mr Google has turned up blank!

Any thoughts guys???

Cheers

only 2 connections? Somewhat limits what it could be.

Is it really two connections, or is there a filament at one end with one wire broken off?

I think this is a tube what can measure röntgen rediation in a rediation counter.

Known as a Geiger Mueller tube.

Similar, but different:

Electronic Goldmine - Glass Type 5980 Geiger Mueller Tube

Apply a large voltage (300 to 1000 volts) across the tube through a large resistor (megohms). Couple the tube to an audio amp or counting device through a capacitor (wiring similar to an electret mic) and listen to, or count the discharge as a radioactive particle passes through the tube.

Ok, but can I put it in a preamp with 20V B+?

 

[DF96]

If it is a Geiger-Mueller tube then I suppose you could include it in a preamp to simulate the almost random clocks and pops from LP.

That is a fantastic idea, DF96. Call it the Nostalginator. Slap a random 12xx7 and some resistors in there and ship it with a pair of really tight jeans. Pairs well with IPA.

Now your talking boys! 🙂

And yes it has two connections only, see photo. Exactly as described in George's link.

Cheers all, will keep my safety glasses on for now 😎
