It's similar though not identical to the 115CR shown here http://www.leapsecond.com/hpclocks/ I'd like to fire it up - given it's age my thought was to use a current limited 24V bench supply and slowly ramp up the voltage the first time - would welcome any thoughts on this. I gather from the supporting documentation for the powersupply it's rated at drawing ~250mA I've been unable to locate a scan of the owners manual or service manual online. Have looked at time-nuts archives, leapsecond.com and hparchive to no avail. There does appear to be a hardcopy available for purchase - happy to fall back to this if necessary, but any pointers welcome. My goal ultimately is to have it on display running, synchronised to a GPS disciplied 10MHz source :) Any thoughts and feedback welcome - this is my first foray into old clocks :) Kind Regards, Hugh VK3YYZ/AD5RV _______________________________________________ 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. _______________________________________________ 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.
