Speedproblem. My wm-d6 walkman goes way to fast! More than twice as fast normal speed 4,75cm/s. Is there anything I can do about it myself or is it a component failing? /Mats

Inside the unit, theres a capacitor or something on the circuit board that has a little phillips head screw area on it, that if you turn it either clockwise or counter clockwise, you can adjust the speed of the cassette playback. This is usually a silver metal thing sticking up somewhere inside kind of shaped like a letter "U'. the inside of the "U' is a round insert like I said with a phillips head screwdriver cut out. just turn that inner piece left or right while playing a cassette to your desired speed.
