Ar300 psu

[ukvince]

Hiya folks... i'm just about done rebuilding an AR300 but need to double check the correct orientation of the zener diode. can anyone tell me if the bent leg is the anode or cathode, or the black ring in the diode would it be at the top or the bottom in Sylvester's photo. ?? i don't want to do all that work and have it fail cuz the diode is back to front.... the one i took out was too badly damaged to tell.

Re: Ar300 psu

For the record, since I'm looking at one of these supplies now, I can state that the Anode (non-stripe) end is (fully) inserted in the hole closest to the IC. But this is also indicated on the silkscreening, which has the symbol with anode end close to IC.
