    I have a noise in the left chanel of the TEAC AG-V3050 amplifier . I can't identify a component : A107
    Is like a transistor . It has a plastic package and It is not exactly a TO92 package , it has two plane faces ( oneof both is bigger than the other ).
    Can you help me?
    Regards, Rafael

    It's a 2SA107 germanium PNP transistor. Those are a common failure that causes crackling noise, and can be found by either heating or cooling the 2SA transistors while the amp is running.

    2SA107 = ge PNP 40MHz
    Common replacements are;
    AF124 to AF127, or AF200

    The noise in this chanel is all the time. Perhaps I need the service manual.

    Thanks again , RAFAEL
