I have no idea where to get it fixed. You might want to check with the vendor. The advertised Electronic Overload Protection should have taken care of the short, the fuse did not even blow
I think you should stick to the Shack PS.
I also think you have a perfect learning tool at your hands. It's a perfect time to get into the electronics hobby, don't you think? I started out that way (wall cubes) then to small regulated PS, then to some basic chargers. Next thing you know you're building custom electronic dischargers already
Tell you what, if you can't fix the problem, build a better output regulator.
Try surfing the net for info. I bet you already have some basic troubleshooting instruments at your disposal.
