*notif : this is mono amplifier. On this schematic circuit power amplifier with IC AN7116 , this schematic only use the IC because its'not have similiar IC. To operate the Circuit , you must have any component's too , such as resistor , condensator , etc. In order to be a circuit that works on good power amplifier. This Circuit requires minimum voltage 3 volt and maximum voltage 9 volt . Ouput power of this circuit is 1 watt, and impedance is 4 Ohm. To see Schematic Circuit ,please see below on figure 1.0 : Figure 1.0 And see Package IC AN7116 below : This package of IC : SIL-9
