I have two 5065a's , both running continuously, one since Jan 2017 and once since Mar 2018. One or the other is monitored every 25 sec by comparison to a 5071a. I've had no trouble with either one. After a few months, the ageing rate is so low its hard to measure, although there are environmental effects. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
