I was tasked with getting my mates Blackstar Fly 3 portable amp going again. I was told he plugged the wrong power supply into it and it stopped working.
It was a fairly straight forward process, the hardest part was actually dissembling it as all the cables were hot glued into place. The only issue with it was the SMD fuse had blown, i’m not sure why they decided to use a non replaceable SMD fuse. I ended up replacing it was a small replaceable one on the off chance it happens again based on an article I found.
Thank you for this post. I found that the “K” mark means a 1.5A/63V fast fuse.
Considering that I can’t easily find that smd fuse, I decided to install a normal fuse holder on the board that holds the DC connector for external power supply.
