    Coke Can Phone Speaker

    Hi, are you trying it on a breadboard or on a protoboard, also is the issue on both amps or just on one? From my experience on breadboards it can always cause issues. If you soldered it on protoboard, I would recommend checking your soldering connections. If it is just on one of the amps, sometimes rebuilding the affected amp will help. I also had a few failed ones while prototyping. If it all doesn't help, please post some pics of your circuit so that I can take a look at them. jsincn
