My OBi1032 phone was supplied without a PSU and I've been using the one from my spare OBi110. The phone wasn't working today and I found the PSU was giving zero volts. No problem to repair - the Schottky rectifier was a short circuit.
However my question is what current rating is marked on the PSU that Obihai supplies with the OBi1000 series phones? The underside of the phone does have 12v DC as part of the case moulding but no indication of current required. (The PSU for the OBi110 is marked 800 mA.)
