Capacitor to fix sound on a Sega Game Gear

[Cornelius]

So I'm trying to follow the instructions here to fix a couple game gears that don't have sound. I'm wondering if anyone has a recommendation for where to find these capacitors. Searching the mfg part number (EEVHB0J470R) pulls up a bunch of places, but they are mostly 'call for quote' or 1000 minimum orders. A place near me (NESS) might have them, but for 2.50 a piece, which seems a bit steep, and I think I need 4 (2 for each GG).

Thanks.

just make sure they are 47 uF. Thats pretty much all that matters. I did it recently and it works like a charm. I bought the capacitators at radioshack for $1 a piece.

make sure the voltage is at least equal to the original capacitors. it can be higher but not lower. i got some 47uf caps for my gamegear out of a dead genesis

Let me see what I've got. If I have anything that'll work I can send them to you. I hunt down electronics parts for my job so I get them for next to nothing.

Thanks for the advice all, and the offer jb. I went the Radio Shack route (I thought they had stopped carrying all of this sort of thing). The guide I was using said the GG caps are 4 V. Not sure the Radio Shack cap says its volt rating, it does have 35WVDC on it... not sure what the 'W' in there would mean. I'm strictly very amateur when it comes to electronics.

Anyway, I did the not as nice GG first, and got sound, but with a pretty bad high whine. It audibly clicks to 'not as bad' a whine when the volume is turned up above a certain amount. And at these higher volumes it isn't very noticeable at all when there is music. I figured it was because of my barely adequate soldering skills, but I did the other cap in the GG and still got the same whine in both channels of the headphones. So I went ahead and did the 'good' GG and it works great. There is a tiny bit of background noise, but I doubt it is any different than a new one was, and I barely notice it. I didn't have one back then, so don't really know.

Thanks again.

Do you happen to have the radio shack part number...It should be on the package. It's possible the caps or the polarity isn't quite right.

[Cornelius]

have it right here: 272-1027.

I was careful about the direction they went in, if that is what you mean by polarity. I'm pretty sure nothing good would happen if they were installed backward, so maybe you mean something else.

[jb143]

Those should work fine. And since you got one working perfectly I guess they do. By polarity I did mean negative going to negative. Sounds like you go got that too. And your right...those guys can actually blow up if installed backwards. At this point I'd guess the soldering might just need cleaned up but I can't tell for sure without actually looking. Best of luck though. Sounds like your off to a good start.
