I have a JK device named a "Thermystal". The label says "1000 KC" 43 MMFD (any age clues there?:-)). So I'm guessing it's an ovenized parallel-resonant crystal which is (was?) on frequency with 43 pf in parallel. This is a fairly large unit, about 1.75 X1.25 X 3.25 inches. It has an ordinary octal plug on the bottom.
Does anyone have any information on this or a similar unit? I've had no luck with Google. I especially would like to have the pin connections and oven voltage, and whether there is anything other than a crystal and oven in the box. If worst comes to worst, of course, I'll open it up and look. Thanks, Bill, WB6JVC _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
