I don't see why you have assumed that one of the capacitors has leaked. The corrosion
could have come from water or condensation onto the board.
I don't see any corrosion on the components.

Subject: Cleaning and Restoring a Badly Corroded PSU
I am now looking at the H7826 PSU that came with a TURBOchannel Extender. It
looks like there may have been capacitor leakage and some heatsinks will
need to be replaced. I have posted pictures here:
https://robs-old-computers.com/2017/10/23/corroded-h7826-power-supply/
So two questions:
1. Any suggestion on how to clean the board? Some of the corners are a
bit inaccessible to reach with just a cotton bud and isopropyl.
2. Do those heat sinks have a particular name/spec that I can search
for?
Thanks
Rob
