The 1.2 A and 1.8 A power supplies are very different as you say. I believe the 1.8 A one was supplied to Apple under contract, hence no schematic 'leaked' from Apple. "Usually" the failure of a Lisa power supply is typical of a switching power supply. (Leaking high voltage capacitors, blown flyback transistor, fried rectifier diode...) so it usually doesn't require a schematic to fix. I suppose there are plenty other failures that cause the power supply to be forgotten on a shelf awaiting repair, I think I have a couple of those. If anyone does find a schematic for this power supply, please let us all know, I suspect many of us care. Otherwise, perhaps someone can volunteer to draw it? (Or even volunteer some funds to commission it) To start, I would suggest Capilano DesignWorks... the lite version is $40, free demo. http://www.capilano.com/ James HNY James MacPhail "Think not of engineering as art, [EMAIL PROTECTED] but of art as engineering" Sigma Seven Systems Ltd.
