Gameboy Color Quality Sound Mod update

Update: new version available for order http://blog.avrnoob.com/2014/02/new-enhanced-gameboy-color-loud-sound.html

Here we go again about sound in the Gameboy Color handheld.

I've made new pcb with new smaller amp ic. So this is a new leaf style cut pcb and it will fit just over speaker in the speaker cutout. Virtually takes no space.
I've already tested it, sounds great. Set to 12db gain.

Here how it looks when wired up. Needs only 3 wires to install (+2 for speaker).

I can make it into a kit now.
