G4 MDD Power Supply Info

[smrieck511]

is there a resource somewhere that tells us exactly what goes wrong with these power supplies when they fail? I would much prefer to repair mine if and when it goes rather than try to replace it. I've already replaced one. Thanks for any help.

@MBongo at Mac OS 9 Lives has a fantastic capacitor list/diagram they compiled for the AcBel PSU. Mine had leaking caps and that was beginning to cause all sorts of power related problems.
