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. https://www.mail-archive.com/[email protected]/msg04732.html
Mark Sims reported on its restoration, and successful operation with Lady Heather. Mark did not report on 1024 week rollover of the M12+ receiver. https://www.mail-archive.com/[email protected]/msg05000.html Frederick Bray replaced the batteries, and worked properly. https://www.mail-archive.com/[email protected]/msg05383.html == 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. https://www.ebay.com/itm/ESE-ES-911-GPS-Master-Clock-Untested-/115123785274 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. == 6 volt SLA battery: Digi-Key # 2059-PC1.3-6F1ND (Zeus battery PC1.3-6F1) https://www.digikey.com/en/products/detail/zeus-battery-products/PC1-3-6F1/9828830 Rechargeable Coin Cell : Digi-Key # P007-ND (Panasonic ML-621S-ZTN) Digi-Key also stocks two solder-tab versions of ML-621 https://www.digikey.com/en/products/detail/panasonic-bsg/ML-621S-ZTN/965124 greg _______________________________________________ time-nuts mailing list -- [email protected] -- To unsubscribe send an email to [email protected] To unsubscribe, go to and follow the instructions there.
