Mkay, so I've got an old MXR Distortion + pedal from the '80s (bought because I'm a Husker Du fanboy and wanted to rip off Bob Moulds guitar sound). And its stopped working

When I hook it up in a chain by itself, everytime I switch it on, it cuts out the amp. Also, when I plug a power supply in I get sparks Not a good sign I would say

Any ideas on how the hell to fix this/what is wrong? I'm a complete noob when it comes to pedals

If you don't solder, take it to a shop. No sense in ruining a vintage pedal.
