I was poking around the web trying to figure out what to do about a time on delay for the PSU of my linestage and I came across this:

I wonder if this could be used as a CCS in a tube amp? Interesting.

Hi,
Gavin,
IIRC those where meant for heater circuits among other things, not high voltages.
Cheers, 😉

Hi Frank. I figured as long as you didn't drop more voltage across them than they are rated for you would be OK. Just something I found while poking around. You would have to be careful when biasing the power tube though. Cheers
Hi,
These where sometimes used to drop voltage in series connected heater strings but I have seen them used in high voltage constant current circuits also. If I remember correctly they consist of a plain iron wire in hydrogen gas. They have not so high Ri and the current regulation is very slow so I dont think they can be used as CCS in an AC circuit.
