    I have a model 1 Sega CD that decided to pop its fuse. (LIKE 5 MINUTES AGO!!) For now I have just bypassed it. I know, not a good idea but hey, the electronics in these things are hard to blow up. So I need advice on the amperage rating and maybe voltage rating of fuse. Form doesn't matter since I have soldering skills and various bits laying around to rig up an adapter of sorts or even put in a fuse holder to make future changes painless.

    On the same note, ditto for a model 2. I have one with a blown fuse as well I'm trying to get reading CDs again...

    The model 1 is from 1992 with BIOS revision 1.10 if that helps any.

    That's annoying when that happens. Usually when you are trying to win too right?
    I've been meaning to replace the fuse in one of my Model 1 Mega CDs for a while.
    When I got it the "fuse" was a blob of solder...
    I used a Littelfuse Pico II 263 Series Fuse – Manufacturer code 026302.5MXL

    FUSE, PCB, 2.5A, 250V, FAST ACTING
    Voltage Rating VAC: 250V
    Fuse Current: 2.5A
    Breaking Capacity: 50A @ 250VAC / 100A @ 125VAC
    Fuse Mounting: Through Hole
    Fuse Case Style: Axial Leaded
    Series: 263


    I picked mine up from Farnell / Element 14 in Australia. Of course if you are outside of Australia / Europe it may not be of much use to you.
    I believe I used one in a Mega CD 2 that had a dead fuse as well.
    Ah yes, I did use the same fuse - here is a video of me replacing it too.

    Good luck getting them back up and running!

    Just get some glass fuses of the right amperage (1.5a was it?) and solder in some fuse holders. Cheap and easy to replace if need be.

    Thank you. That's what I was thinking. I have those items.
