There is next to no info on these beasts. I have one working, and one with a missing driver board that I can hopefully remake.

Do you have a picture of the boards? Do you know if they are the regular PASS A40 boards? I have some A40 boards from back in the Audio Amateur/ Old Colony Sound Labs days. I also have a stash of the unique Lambda Darlington output transistors. I built an A40 in a SUMO Andromeda II chassis years ago and still have it.
