[Milsurplus] I-81-A Radio Compass Indicator

[Al Klase]

Antonio,

I'm sure it's designed for 400 Hz, and I believe 115 VAC.  See:  
http://website.lineone.net/~norman.groom/SCR269.htm

You might be able to get away with lower frequencies at greatly reduced 
voltage.  I know some people did so in the "old days" for ham use.
