Klystron??

I have a BIG tube(G.E. JAN-5948). any idea what it is/ what it's worth?

 

[Frank Berry]

The tube is a hydrogen thyratron. It is used in many high powered Radar transmitters.

I belive "imix500" on this website has a shematic for the JAN-5948
but It is for a "Thyatron display" goodness knows what that is, probably a light show thingo..

Only reference I can find to the behemoth

 

[kevin gilmore]

think of it as a very large very high voltage very high
current scr. Absolutely useless for audio unless you
intend on using 4 of them as a primary switcher for an
audio amplifier in the 100kw range.

so that thing works in avalanche mode? hmmm.

and if I'm seeing things correctly, is the tube "double-walled"?

 

[imix500]

Yup I have one just like it, except yours is in a bit better shape, probably a newer build. I just have mine set up to glow, with a 200w load across it.

 

[imix500]

The specs I have say it will switch 11MW!!!
If you find you don't need it let me know.

Thanks for the info everybody. I'll get back to IMIX when I get a chance.
