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
doesn't seem to have those particular schematic diagrams.
For your enjoyment the part which smoked.
I certainly am glad I have the lid off while testing. Unfortunately these
capacitors which appear to be film type were hidden from view.
The fuse didn't blow, but that .22uf 250v capacitor certainly stunk up the
house. It smelled like burnt popcorn, plastic and the bottom of a coffee
pot which has boiled dry, yech!
I know that if I had pulled the power supply board first I might have seen
the physical cracks in these boxed capacitors.
Wasn't it Marc V. that said in one of his videos, you don't need to shotgun
them all! Oi, lol
It's when things like this happen that I most always worry about not going
over vintage equipment fine tooth comb.
