Apple IIe power supply help

["Erik" <erik@rmwt.net>]

Trying to help a friend out with an old Apple IIe (built 1983) that has
quite working, have isolated it to the power supply, power into the supply,
power at both sides of the switch and the fuse is good, but no power out.

I would assume finding another power supply is a lost cause so we are left
with repairing this one, but have no schematic for the power supply board.

Does anyone out there have access or know where I can obtain this?  Any
would be greatly appreciated.
