Hey guys, Fixing a friends PS1 as it had a ringing power supply and was smoking a little. I have found that one of the zeners on the output was shorted i have removed it and powered it up and the psu now works but i need to replace the zener. Does anyone know what the voltage of the zener is? Its listed a d103 / MAZ9120D0LS0-TX/L on the schematic and on page 21 of this manual. Every time i google the "part" number i just get linked back to psu manuals.
