I think at tda2822 will collect much more reasonable .. yes, and the volume and power will be better. depending on the power supply will be from 0.5 watts to 2 watts


R1,R2-10k; R3,R4-4,7Ом; C1,C4,C5,C8,C9-100microF;
C2,C3-10microF; C6,C7-0,1microF; DA1- TDA2822 (KA2209,NJM2073,U2822,U2823).
power supply 1,8-12V.
