    has developed noise in the right speaker. it has already been switched to
    110. the plugs only have two prongs and an adapter is used. may have picked
    up some static. is this the possible problem? it worked fine for the first
    two weeks and screwed up when a tape deck was connected.

    Hi there,

    sounds to me like you have contracted a ground interference via the cassette
    deck connection.
    As European low-power devices have no ground prong (usually), their input
    jack local ground may float at some potential. If you are using a cable that
    has its shielding connected to both sides current can flow on the shielding
    which may induce humming or crackling noises.
    I do not know a definite solution for this problem. If the noise disappears
    when you disconnect the cable this is the reason, otherwise you may have an
    electronic fault.
    A suggestion is to insert a larger capacitor into the shielding of the cable
    to block direct current.
