This is a replacement board for the Original Game Boy(DMG) headphone jack.
With all new components this is a perfect way to replace the old worn out capacitors and save space for other mods.
You can purchase this kit in two different ways:
-Basic kit: PCB with components only(no headphone jack). You will need to remove your original headphone jack and install it in the board.
-Full kit: Assembled PCB and includes an original headphone jack.
Easy to install. Desolder the wires and headphone jack from the original headphone PCB and solder them to the new headphone board in the same order.
You can also use the DMG Audio as an internal prosound by only soldering the right two wires(ground and switch) as they originally were and soldering left and right to the volume pot.
