2 X 40 Watt STK amplifier
Components of the above is one component of ic which is applied as a reinforcement. Power amplifier used in an audio signal in order to become more powerful and can be heard via a tool that is the speaker. But in each set must have a voice amplifier, voltage, power quality is different.

70W STK amplifier schematic
For this amplifier circuit using three voltage plus, min, and the ground. with a maximum voltage approximately 55Volt DC. And amplifier circuit can use some ic ie IC STK 030, 058, 075, 077, 078, 080, 082, 083, 084, 086. From all the ic I mentioned all of them can be applied to this amplifier circuit. But every ic whether there might be a different maximum voltage or power output, etc.. For this amplifier suitable for use at home, who need a voice soft and tasty. With a maximum output of 70W 8ohm impedance is my take of the highest IC output is STK086.Part List
R1 = 1K
R2 = 56K
R3 = 100R
R4 = 100R
R5 = 56K
R6 = 4.7R
R7 = 2.7K
C1 = 1uF
C2 = 470pF
C3 = 100uF
C4 = 100uF
C5 = 0.047uF
C6 = 47uF
C7 = 1800pF
C8 = 10uF
IC = STK 030, 058, 075, 077, 078, 080, 082, 083, 084, 086.
