Ohhhoooo so very shiny! I discovered one of my Sega Mega-CDs has a blown fuse that someone replaced with a big blob of solder.

It certainly passes power that way, but the fuse is there for a reason. I want the little guy to have its proper overcurrent protection back, so a little bit of research led me to this:

LITTELFUSE - 026302.5MXL

  • PICO II 263 Series
  • Current rating: 2.5A
  • Voltage rating: 250VAC
  • Response: Very fast acting
  • Mounting: Through-hole
  • Package: Axial leaded
  • Breaking capacity: 50A at 250VAC

This is the replacement I selected for my PAL unit. Another hardware revision or region may use something different, so check the board and service information rather than assuming the same specification.

Anyway element14 has them for a few dollars each. If not element14, you could always try Farnell since they’re the same company.

Looks pretty good to me. I should have my hands on them early next week.
