I don't know that there was ever a schematic available for those, I've seen a lot of Quantar manuals and they all had just the block diagrams. They were only meant to be serviceable at the module level, that is to say, they give you enough information to determine that the power supply is bad, and then you replace the whole thing.

I can confirm that there are no schematics for any of the various models. There supplies were built to a functional spec by different vendors and each used a variation of their own design.

Many are quite fixable depending on the fault but need to be tackled with experience. Some need to have rivets drilled to gain access.
