    40 Watt Power Amplifier Circuit With TDA2030

    Power is 22W into 8 ohm speakers and 40W into 4 ohms. Distortion is 0.012% at 1 kHz / 8 ohm/11W and 0.032% at 1 kHz / 4 ohm/20W. Curent Offers variates IC1 ultimately for the input audio signal, so there will be a similar variation on the R6, R7, R8 and R9. Until the current is close to 1A...
