    I have new looking Sony Walkman WM-FX999

    It plays like new thanks to a new belt from Marian. [​IMG]

    The side A plays fine but the right channel is alot quieter than left channel.

    I can hear almost mumbling sound too only on the right channel.

    Side B is perfect.

    I presume Side A and B would use the same audio circuitry on the board.

    thanks

    Yes and no. All Autoreverse Walkman I have seen use a 4 track head so the signal path for side A and B will be different around the heads.
    It is also possible that there is a problem with the tape path, for example something causing the tape to not touch the head properly on just one side.
    The mumbling you hear could be a trace of Side B being played backwards.

    This model has 2 separate heads for playback A and B and only 1 pinch roller in the middle.

    I see what you mean

    according to that only four Walkmans ever used that arrangement.

    It actually makes it more likely that one head of the two heads is out of alignment.
    With a normal four track single head Walkman at least you know that the spacing between the tracks is going to be correct.

    With this one I presume there must be azimuth adjustments for each of the two heads, and you could have one direction set perfectly and the other direction way out.
