They work like a switch. They are either on or off, and once they are on they stay on until B+ is removed. They are the vacuum tube equivalent of an SCR, or half of a Triac. They do glow purple when they conduct.

If it glows purple then maybe I could incorporate it into the 807 amplifier I'm building maybe as a voltage regulator or something.
perhaps to regulate the voltage for the 6AU6 driver stages in my amp.

Whats the circuit.
I'm building a version of the Tabor circuit with those valves - i would be interested in how your using yours. Got to the build stage with mine - should be about a week before I have any results.

Hmm well from research I did it seems it's a mercury tube and it glows blue, and I don't think I'm really too competent in designing a circuit for it or even if I'll get much benefit out of it. My amplifier is essentially done and it's a bit too much of a hassle to incorporate this into it. I've never worked with tube regulation for power supplies. Hopefully I'll have my new amp fired up in a day or two.

Turn it up till it explodes - then back up just a little.
