Nevermind.. I found the complete schematics. Here's the forum thread:

and the file:

And the PSU by itself...
I am also in need of the MK IV schematic that has the power supply section and hoping that the voltages are marked too, either version but the first one is preferred. If you have both, please send both.

Much appreciated.
