Time Nuts- I have an Austron 2110B with a dead power supply. However, the 2110 power supply schematic that was on KO4BB is not correct for this unit. That power supply schematic is all discrete parts and a few ICs. This unit has a Vicor VI-223-CY 36V power supply module followed by 3 Packaged Power modules plus other circuitry. The main transformer/bridge is fine as is the VI-223-CY. Something past that point in the circuit is not working. Anyone with a schematic for the 2210B? Thanks- Jim

Jim, Here's my info on the Austron 2110B: http://leapsecond.com/museum/au2110b/ps.htm http://leapsecond.com/museum/au2110b/lcd.htm http://leapsecond.com/museum/au2110b/pics.htm The first link shows, I think, the older schematic you refer to. The 3rd link are photos of my 2110B, which has the newer power supply and backup batteries. Let me know if yours is the same as mine and I'll hunt through my Austron manuals. /tvb On 9/19/2024 5:27 PM, Jim Schatzman via time-nuts wrote: > Time Nuts- > > I have an Austron 2110B with a dead power supply.
