Help from pedal fixers, please!

Hello y’all! I just picked up a pedal free from a person I met a show, it’s and Aguilar Agro and it has a burnt out power supply. All I know is that the guy accidentally plugged it into an 18V power supply instead of a 9V and ever since then it hasn’t turned on. I’ve taken it apart but I’m not sure what I should be looking at replacing to get it back running again. Anybody have suggestions? I would guess there is a fuse that needs to be re-done, but my expertise doesn’t apply to pedals and pc boards.

I’m sure I could send it back to Aguilar and have them do it, but since this is a free pedal and I want to learn a little bit I’d like to take a shot at it myself. Always good to get some action with the soldering iron! I’ll post some pictures of the board so you know what I’m looking at. Thanks in advance!
