I always play with headphones on and when playing my GBA I would always have a slight but noticeable buzzing sound that you all should be familiar with, especially if you did the amplifier modification.
the dehum dehiss kit already provides a sort of solutions to this problem but i think that isn't nearly good enough. I can still hear the buzzing very clearly, especially through my headphones.
That's why I always carry a ground loop noise isolator with my GBA. And with it the noise is nearly gone, completely unnoticeable when ingame. But having to constantly hold it in the hand at the same time with the GBA gets cumbersome and uncomfortable after a while so i was wondering if it was possible to fit one of those isolators into the GBA, I've certainly not seen anyone else do it before.
I've taken one apart to get a better understanding of how the components inside are arranged and how well they could actually fit and from what i can tell its just two of these little coils and the 3.5mm jacks. The jacks wouldnt be needed if one were to mod it inside obviously so its down to those coils.
But that's about were my knowledge ends already. Looking at the PCB it looks like some pins of these coils are either completely unused or, more likely, the PCB has at least three layers where those remaining traces are. But i don't know jack about electronics so i would be glad if someone that does could chime in a bit.
