[Gregory Beat]

October & November 2019 (on time-nuts), I reported on surplus ESE ES-911/GPS Master Clock units being sold by an East Coast reseller on eBay.

Mark Sims reported on its restoration, and successful operation with Lady Heather.
Mark did not report on 1024 week rollover of the M12+ receiver.

Frederick Bray replaced the batteries, and worked properly.

Another ESE ES-911 unit appeared on eBay, auction # 115123785274 from an Marina, Arizona reseller (habitualreader).  The unit is missing its 6 VAC Wall Wart power supply (sold for parts), seller accepting offers.

Shipping costs are High, possibly local Arizona time-nut bargain (pick-up).

It does not have the Ethernet module installed (WizNet) or the 10 MHz output.
** You can request the ES-911 Manual with full schematic and parts list from ESE. **
Bench savvy “time-nuts” could Add missing options (unless u-processor controlled/firmware)

Assume the two (2) batteries are DEAD, and require replacement.
