Dehum/Dehiss Kit for Game Boy Advance
This little kit is perfect for fixing the hum that the amp will likely make. I installed it correctly the first time, and within about 15 minutes or so, it it really is an easy install. I did have some trouble getting the capacitor that goes to the headphone jack in the corner of the board but, if you're willing to cut the legs short and attach wires from them to the solder points, the cap will lay nicely sideways under the "CE" of the logo, left of the speaker.
I want to end with a beginner's warning and advice on the small surface mount capacitors. They are SMALL! They are tough to put on! If you start by adding a some flux and a small glob of solder from the tip of a fine point iron on the C15 cap that is already there, then place the additional cap (already fluxed) beside, hold the new cap down in its middle by the leg from a larger cap, then gently sweep the solder glob over, you'll be golden. You can do it, it will just take a little time.
After the frustration of the little caps is over, it is definitely a rewarding modification, and I whole-heartedly recommend it.
I think this kit did make a small difference in noise, but I cannot recommend it. The surface mount caps (the little ones) included are NOT the ones shown in the pictures. The ones that they actually sent were SO much smaller (like, large grains of sand). Seriously, I used to work in pro-audio and these are the smallest components I have ever seen. I may end up trying the mod again in the future, but I will probably be buying my 1uf and 10uf caps elsewhere so that I can get usable sizes.
Additionally, the photos in the guide show and additional cap soldered to C6, but does not mention it in the text. I'm not sure what to make of that.
Ok, so obviously the large capacitors are easy to install. Yes. But the micro-sized ones? No. Unless you have a magnification setup, a very fine tip for your soldering iron, and very fine tweezers, in addition to the precise hand-eye coordination to do it, don't even attempt this part of the mod. It's very easy to accidentally desolder C16 and C6 when trying to add the extra capacitors there. And if that happens, it's almost impossible to solder them back. Now I have to buy another GBA and grab the PCB from it. I'll salvage the big caps from this one, but I won't even remotely be trying to solder these 1uF or 10uF caps ever again if I can help it. They're the size of the tip of a ballpoint pen.
It did reduce the hiss and hum a bit, maybe by half. Definitely still there though. It seems that in fixing the headphone audio though the speaker now crackles a lot. I would just skip this mod honestly.
Installed on my gba and it does what it claims to do.
