Simple 12v Audio Amplifier Circuit. Full video making of this 12volt power amplifier circuit by using pc power supply former the input voltage about 14v dc asymmetric with current output 5a 20a. What you need to build this 12v audio amplifier tip35c transistor resistors 1k 16v 100uf capacitor 12v battery speaker download circuit http.
They are used power supply voltage 9volt only. It is just a 3 component amplifier. The audio quality is really loud from the amplifier.

They use transistors example number is ac176 ac126 and bc109. But provide higher watt power to 54 wrms at load speaker 4 ohms and there is distortion at 1 and watt power maximum 65 vrms at distortion 10. They are used power supply voltage 9volt only. For the final transistor is using d1763 and b1186 you can also using tip31 tip32.
