I remember that on the NASA Manned Flight Tracking Stations during the
Apollo program, inside one of the racks of the timing subsystem was a
big Marantz HiFi amplifier. It was used to amplify a 60 Hz signal
derived from the Cesium reference to drive the common wall clocks that
were in many places. Of course, the operations time displays were digital.

I collect clocks an have many clocks with 60Hz Synchronous Motors.
How would I go about Disciplining a 60Hz 120VAC source from an
Unintteruptable Power Supply (UPS)?
This would solve both my problem with power outages and the new problem
of possibly undisciplined power from the power companies (Henry Warren
must be rolling over in his grave!)
I have no Idea how you would disciple such a low frequency at such a high
voltage and
deliver the power required to drive several (or many) Clocks.
I assume you would start with a commercially available UPS and either a
disciplined 1 Second
or 10Mhz source such as a thunderbolt (also powered off the UPS or the
batteries in the UPS).
Does anyone have an suggestions for circuits which would do this disciplining?
Thanks
