The schematic of this PSU block has been printed in many field
maintenance printsets -- I normally use the one in the 11/45 printset. So
yes, I do have the schematics.

What I don't have is a scanner, so it's not going to be easy to get them
to you. Are they not on the web somewhere -- I can't believe that none of
the scanned printsets out there include this PSU.
