This is the scheme diagram of 5W audio power amplifier which can be built for general purpose and can drive speakers approximately 8 to 12 inches. This 5W audio amplifier circuit is based on the Sanyo LA4460 IC. Based on the IC datasheet, the LA4460 has capability to drive up to 12W power output, of course you will need more power in your power supply.
This Low-power amplifier circuit have built in loudness control, driver amplifier Q1, and the bass/treble controls of around ± 10 dB boost / cut. It would be useful in a wide variety of situations. Either displayed ac supply can be used, or 12 VDC supply can be connected to points A & B (positive) and C (negative). For stereo circuit can be used two of this circuit by using ganged potentiometer at R2, R7 and R11. T1 is 12V at 1 ampere plug-in transformer.
