Small audio amplifier IC 7w using lm383

This circuit, will help expand the sound small. such as radio, sound out, including CD WALKMAN. To the more powerful sound.The amplifier circuit can be up to 7 watts. Enough to use a good listening room.And most importantly is a very simple circuit.
Operation of the circuit. be Input signal is coupling with the C1.Passed into the pin 1 of IC1 number LM383. Amplifier output from the pin 4.Through C3 increase in low frequency stability better, before leaving to the speaker. The R2 and R3 set the gain 100 times. Which is calculated from the (R3/R4) +1.The C2 functions help in frequency response.
