DIY amplifier circuit diagram using TDA2030: This is a DIY amplifier circuit diagram using a TDA2030 IC. it’s a mono audio circuit, so the stereo needs a dual board. We can use 12-0-12 voltage to 18-0-18 voltage and 3 amperes on this board. we can get 30 watts using 15-0-15 voltage. positive negative and ground … Continue reading DIY amplifier circuit diagram using TDA2030
