If you like to listen to music a comfortably ears. Want to create a your power amplifier projects with yourself. This project will direct your heart for sure. By the power dissipation of 20 watts at 8 ohm or 30 watts at load 4 ohm. And easily without any adjustments and Cheap because We use the three tiger army.
As shown figure the
circuit, you know 3 soldier that from one IC-TDA2030 and two transistors (TIP41,TIP42 or 2SC1061,2SA761 or BD908,BD907) for helping to extend the signal up there. Part other equipment is useful Likewise.
When we enter the power
supply and sound signals into this circuit. The capacitor C1 will prevent DC voltage through it. Therefore, the sound signals is at pin 1 of IC1 easily. And This circuit use a single power supply that has two terminals are positive and Ground(negative),
So must be connected two resistor R1-56K, R2-56K and C2-47uF to divide the voltage by half. The R3-56K is the result matches the input IC1. ??Gain of IC1 in this circuit is set as High to 14 time. By setting this circuit to the non inverting amplifier circuit or not inverting there.
