    6) 5 Watt Class A Amplifier Circuit. This class A amplifier circuit produces 5 watts rms into an 8 ohm load, however it needs a supply of 22 to 24 volts at 1 amp. This results in a maximum efficiency of around 19%, which is lower than 1/3 …

6 watt Audio Amplifier Circuit Using TDA1011 - …

    https://www.homemade-circuits.com/6-watt-audio-amplifier-circuit-using/
    A monolithic integrated audio amplifier circuit TDA1011 is especially used for recording systems or portable radio. TDA1011 has the power to delivery up to 4W on an impedance of 4W load. The device can also reach 6W on 4W where the supply would be 16V in those applications which are mains-fed. The maximum permissible supply of TDA1011 is 24V.
