Hi! I have repaired several DD walkmans, all with succes. Unfortunately, a WM-DD from a friend of mine, has severe circuit board issues resulting in issues with the left channel. The batteries have leaked onto the board, but also the board is broken on two places, resulting in several broken traces. I tried bodge wiring the broken traces, but that didn't solved the issue. Also, i replaced all capacitors, cleaned the volume pot, desolderd and resoldered the 3.5mm jack plugs, cleaned with IPA, checked the wiring from the heads etc. Anyone on the forum that has a spare WM-DD board and is willing to sell? Please contact me, Kind Regards, Roland Duursma The Netherland
