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.
I had a very noisy gba. Installed this and new capacitors and the buzz and hum are 95% gone.
I got this kit to try to tame the very loud hum and noise the GBA produces for better audio recording. The soldering is a little tricky with the tiny capacitors, but overall not so bad. The results are great! I can amp the GBA audio up to good levels now.
The kit doesn't remove ALL of the noise. For me, all that is left is a very soft hum that isn't audible unless amped up to very high levels. I'd say the noise floor is cleaner than a pro sound modded DMG.
Got rid of the annoying high hiss. A must have for your sanity
