SNES Factory Spec Power Fuse
One High Quality 125v 1.5a Fuse which can be used as a direct replacement for a blown fuse in a Super Nintendo Entertainment System. The install will require a 4.5mm security bit which can be bought on eBay cheaply.
If you have already checked your AC adapter and your Super Nintendo still will not power on you most likely have a blown Pico fuse. Simple to install with basic soldering required. Quick installation guides are available online.
(This fuse will not fix every broken SNES, only a SNES which has blown its internal 1.5a fuse but is in good working order).
