I own several very useful DEC "Leprechaun" Boxes, e.g. RD54-DB, RD53-DB, TK50-DB, RX50-DB, but in all but one the Power Supply has failed.
Has anyone got the Maintenance Print Set (sorry, I don't know the number) or just the schematics for the power supply?
Sorry, don't have that info. FYI, though, if you didn't already know, the power supplies for these do need a load to start and regulate properly. I had one that I thought was bad, that I was testing with no load on it, and thought it had failed. I stuck a disk in and the PS worked fine after that.
