New Enhanced Gameboy Color Loud Sound mod

NEWGBAmp3 is available, includes headphones support (mute speaker).

New enhanced version of Gameboy Color quality loud sound mod is ready. It's called GBAmp2s. It's ready to order at

Difference with the previous version is that it is using different amplifier ic with more gain. Also it uses stereo audio signal from Gameboy. And you do not need to install additional capacitor to remove loud hiss/hum from the speaker. A bunch of quality capacitors already installed on the GBAmp2s mod pcb.

And here how it looks installed in the Gameboy Color:

Yes there are couple more wires to get stereo audio to pcb. This new pcb design has all connections marked on silkscreen, so it's easier to install.

New pcbs are made by which service I will review later.
