This is a simple project, based on the LM1895 miniature amplifier, followed by passive components.In this way, outputs of 10mW to 1W are obtained. The circuit is called a miniature amplifier.The output of the mic or preamplifier is passed through a variable resistor VR1 and a capacitor C4.Variable resistor VR1 is used to select signal strength.
