I have an old, but looks just like new, General Radio FR46/URM-18 Frequency
Calibrator.
It is a rack mount and has a metal container that has inner box that is an
oven. In the center of the oven is a suspended quartz block, hung by spring
like devices in all directions. The front panel has a thermometer that
reads the temp of the oven. There is also a meter on the front panel marked
0 - 200 Micro amps.
There is an electronics deck in the rear with a couple of tubes, and a
adjustment pot. There are a pair of cables with large military type
connectors hanging from the back of the unit. One goes to the oven box, the
other to the electronics deck. I expect that would be the connections for
the external power supply, that is not part of this panel.
Does it have any value? Something that I should put on eBay? Or should be
tossed in the dump.
It is such beautiful workmanship, it seems a shame to just toss it out or
destroy it.
Thought and ideas please,
George
