These are pictures to help with assembling when you use the WM-3060 walkman with the ?* kit.
Remove screw in red circle.
The slide connector for the flex cable can be moved horizontally then you can pull the cable out, it should come out easy. Put it back when you put the walkman together again.
Remove resistor TH60 (10k resistor in Yellow circle, hold your soldering iron with solder on the tip on the resistor till its solder melts and move slowly away from the PCB, it should stick to the soldring irons tip).
Solder the wires to the walkman like in the above picture.
Solder the components to the PCB, cut all legs short so it sticks good to the walkman with the double sided tape. Check the zoomed it picture for where what parts go's, the 100k resistor is replaced with a 68k resistor.
Solder the wires to the walkman in these places, and with these colors.
