TDA2005 2 X 20 Watt Power Amplifier
This time, there is a series of audio amplifer 20W as well, but using IC TDA 2005 as a series of his base amplifier.
The series of 2x20 Watt Audio Power Amplifier using TDA2005 can you see in the picture below.
The series of 2x20 Watt Audio Power Amplifier using TDA2005 can you see in the picture below.

9 20 Volt amplifier circuit
For this time I will post the scheme following an amplifier of the IC KA2203, SN16975, TBA820, UL1482P. Which has 4 Watt power output with 4 Ohm impedance. At least 8 Volt supply voltage and a maximum of 20 volts.Part List
R1 = 100K
R2 = 56R
R3 = 56R
Use 1/2 W resistor
C1 = 47uF
C2 = 100uFC3 = 100uF
C4 = 470uF
C5 = 470pF
C6 = 0.22uF
C7 = 100uF
U1 = KA2203 , SN16975, TBA820, UL1482P
