New York Audio Labs - Moscode Super It Phono Stage

Hi - just wondering if there is anybody out there who has or has had this particular NYAL Phono stage. Unfortunately, mine has a defective wall wart power supply, and the tech who tried to fix it does not know the value(s) of the step down and I also believe step up voltages, so I'm somewhat in limbo. I'd really appreciate it if anybody knows where I might attempt to replace this transformer, or have a schematic perhaps ? Thanks very much.
