Sudden strong noise from the analog OpAmp
I am building a device that works like a phonograph. I am using a piezo disc as a microphone and a pcos3 kit for the amplifying, filtering and processing . But I a getting a terrible sudden noise at the output of the OpAmp for some seconds.
Maybe somebody knows the reason?
I attached the amplifier circuit.
