[cctalk] Schematics for Lear Siegler ADM31?

I've checked bitsavers.org (Al does a great job!), and a number of forums, but no luck finding schematics for my ADM31 that I am trying to resurrect. The power supply has issues and I need to identify a blown out resistor - the switching supply is a Boschert model 1001 date code 7943 Revision J.
