Sega CD Model 1 fuse?

[lilmul123]

I just picked up a Sega CD model 1 with a dead F1 fuse. Most guides I've read online say that the model 1 uses a 1.5A fuse, but the one that is already there is 2.5A. Why the difference, and which amperage should I actually replace it with?

There's no real reason for the difference, other than giving the Sega CD a bit more amperage headroom (not that it would help if the AC adapter isn't outputting more amps or there if there's no extra amp load on the system). You don't need to replace the fuse that is already in there, it'll do fine. Unless there's a serious problem with the system, it'll only pull as many amps from the power source as it needs. What the fuse usually protects against is poor quality/unreliable voltage, reversed polarity and too much voltage. I put a 2.5a fuse in my Sega CD Model 2 and it's just fine. It's all I found that was suitable when I bought fuses too.

I'll stick with the 2.5A then, thanks!

I wonder if someone could post a pic of the board where the fuse is?

Guntz ain't that be CD2 fuse location. I thought he asked Sega CD model 1 fuse location. TBH you could read these things in Sega CD system repairs thread also ))

Oh, whoops, forgot this was a Model 1 thread.

Then again, the guy didn't really specify which model he needed.
