5 8 Watt audio power amplifier
This amplifier circuit has a power output of a small or too low at 5.8 Watt, which uses IC KA2205. The required voltage for at least 6 volts to 18 volts DC maximum.
Schematics power audio amplifier with IC KA2205
Component List
C1 = 1uF
C2 = 100uFC3 = 47uF
C4 = 1000uFC5 = 0.1uF
C6 = 220uF
IC1 = KA2205
