eBay item 150082419799 (Genrad 475-C)--is this some kind of OCXO frequency reference? From the description, it sounds like it might be used to monitor a broadcast transmitter frequency. Be sure and scroll down and check out the wood and foam oven box and the "quartz plate" resonator.
The '56 GR catalog at the bama site doesn't show a 475-C, but that's not surprising as the 475-C looks quite a bit older. -- newell N5TNL _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
