On the amplifier circuit using ic STK, the same as my previous posting. However, in the above circuit has 2 inputs and 2 outputs, or commonly called a stereo amplifier. This issue of power amplifier 2 x 18Watt and has impedance 8. To stress that it takes about 35-38Volt.
Resistor
R1 = 390K
R2 = 390K
R3 = 220K
R4 = 220K
R5 = 220K
R6 = 220K
R7 = 100R
R8 = 1R
R9 = 9.1K
R10 = 9.1K
R11 = 1R
Capacitor
C1 = 10uF
C2 = 10uF
C3 = 0.47uF

C6 = 0.047uF
C7 = 4700uF
C8 = 100uF
C9 = 1000uF
C10 = 100uF
C11 = 4700uF
C12 = 470uF
C13 = 0.047uF
