Game Boy CleanAmp v1.2 Audio Amplifier Universal - RetroSix

great mod

The amplifier works great; the instructions though, may be a bit unclear. It seems, there should be only one wire from the volume wheel (centre pin) to the amp chip. Nothing should be on the centre vertical pad on the pcb. I could be wrong, but removing this wire is how I got mine working. hope this helps.

A quality mod

Best and needed mod for gba it’s perfect

Overall, good mod for the DMG-01

So I ended up grabbing a new power regulator along with the audio amp. Right now, I'm using the factory speaker that came with the Game Boy. Overall, quality is good and sound is effective (and very loud). Since I was careful and used plenty of flux, I did not run into any issues with the quality of the solder pads on the board. A few improvements for this mod and the offerings of items on Handheld Legend: - The directions for the DMG-01 install have me solder a small wire on the end of a component (resistor or capacitor. Not sure). If we are having pads on the board already, why not just have another pad available to solder onto? Even when being careful, I still shifted the component. This part of the design introduced unneeded risk for the install - Handheld Legend offers new speakers. Cool, except the wire length was not adequate for this mod. If I missed another item posting to get a new speaker with longer wires, that should be a more obvious option. Otherwise, consider defaulting the speakers sold with longer wires for things like this mod. Due to this, I just stayed with my original speaker - I'd like to see recommendations for taking advantage of the increased power output of the amp. Better quality speakers? Higher impedance headphones? Is this mod a good direction to take for an audiophile Game Boy? - It wasn't clear to me if this amp would clean up any of the white noise on the audio line (it doesn't, at least on the headphone output. Makes sense, but still). Perhaps a specific disclosure on this only amplifying total power of the output would be good, especially given the name of the mod (CleanAmp). That's all I got. I'm a happy customer, but think there is still room for some improvement on the mod itself and how it's sold.
