The schematic is 40 watt audio amplifier pretty simple; the TDA2040 is amplifying the signal and providing 25Watt RMS wattage. Additional power amplification is done using BD711 and BD712 transistor pairs. Input capacitor 470nF is the DC blocking capacitor which will only allow the AC signal to pass. One major thing is the Single supply voltage.
