    I have a Bluetooth speaker and have some trouble finding parts.. One chip has
    C4558
    St GZ2 and other chip has
    AP8203MF
    AvPlus
    Z2106.. The chips are connected to audio amp side I think..


    Thanks for any help..

    4558 reminds me of an old op-amp. Many pin-for-pin replacements are available. Or was that a 4550? Darn senior moments!:mad:

    Yep. JRC4558 dual op-amp.
