200W Amplifier Circuit TDA2030 New PCB

| 2011/11/20

I think there is no one who knows the 200w amplifier circuit, whose power is increased by connecting 2 TDA2030 power transistors to its outputs. I first saw this circuit in the elektor in the 2000s. There was a thin and long PCB printed circuit drawing. It worked very well. Actually, my purpose in making…
