Apple Lisa PSU Build

Dave Luna Dave Luna
Last year, Santa gifted me a beautiful Apple Lisa 2/10. It came with electrical problems, and I spent weeks unsuccessfully troubleshooting the original power supply. I finally got it working this weekend after replacing the original power supply with Warmech's ATX-based design that I assembled from off-the-shelf components.
 
This Lisa was converted to a Macintosh XL, but my plan is to switch it back to a Lisa 2 configuration.
Oh, hello.
