Battery bombed IIfx PSU repair

[robin-fo]

Hi everyone

I recently got a IIfx with heavy battery damage. I‘m not planning to restore the logic board, but I‘d like to put a Mac II logic board into the case and restore the original PSU. Despite the horrific appearance of PSU case, the interior looks ok. Well, except a blown fuse and an exploded capacitor.

Any thoughts about how much work this might be? What could be the reason for the blown cap and fuse? What else could be damaged?

Thanks!

A short / bad component somewhere. Test the diodes on the high voltage side.

There are probably a few ATX based PSUs that would fit in the same enclosure.
