These are pictures to help with assembling when you use the Retekess TR606 walkman with the ?* kit.
This walkman sounds good, the volume is loud. It is not ideal for use with this kit because it has another chip in it then the other walkmans. To make it work i added a extra resistor to the PCB to make it work quite good.
Remove resistor R29 (it is next to the brown wire).
Now solder the wires as in the image above.
Now everything can be screwed back together and it should look like this maybe.
