A replacement headphone jack + mono amplifier for the DMG.
An updated version of this board is available on GitHub.
I designed this to have an easy replacement for the aging headphone jacks.
Feed L + R directly from the volume potentiometer, connect GND, VCC, the speaker.
You can connect VCC either from the battery (after switch) or regulated power.
Adjust the trimpot to reduce the power draw (and max volume) of the amplifier.
Picture of installation.

Notes
The headphone jack outer diameter is a bit smaller than the original. A 3d printed part should be added to close the space left behind.
