I've certainly got some for sale; mostly DS/DD but a few SS/SD as well. Can
your drive(s) handle DS/DD disks?

Side thought: I had one of those blow up on a BA23 chassis a few months
ago. When I opened the supply it was full of aluminum paper from the
inside of the cap; glad it didn't short out any other components.
Remove and replace.

If the PSU requires too much hacking, you may just want to replace with a
modern Mean-Well switcher or two. The Aztec supplies used in those Xerox
enclosures are OK but nothing stellar. I recapped mine (it also showed signs of
electrolytic leakage) and it did work so I kept it, but if it'd had

Yup, always replace. These are not parts that can be rehabilitated.
You shouldn't need a schematic. These thin film caps are a common
failure mode on a multitude of PSUs. Just replace like for like. Thin
film X and X2 rated caps are easily found from your favorite electronics
part retailer.
If it's gold and got RIFA on it, replace it, though. Just because
Where might I find a schematic diagram for the Xerox U07 8" FDD,HDD
expansion cabinet for the 820II, and/or the 105P80450 power supply?
The Xerox Professional Computer Technical Reference Manual I downloaded from
bitsavers.org doesn't seem to have those particular schematic diagrams.

It had tapes containing terminal programs to access different types of
systems. And the instruction set was said to be similar what became the
