STK 4050 200Watt Power Amplifier Circuit

Amplifier circuit with IC STK is tough and good quality. In this article an amplifier circuit with IC STK another base. Power "Amplifier 200Watt By STK4050" is an audio amplifier of the STK family with 200Watt power. To create a power amplifier with the STK4050 IC is not require many external components.

Power Amplifier uses symmetric 30Volt power supply system. Power Amplifier With this STK4050 can reproduce the power 200 Watts at 8 Ohm load spaker. In making Power Amplifier 200Watt With this STK4050 do not forget to provide adequate heat sink for the IC STK 4050 in order to avoid overheating.

Schematics Amplifier STK4050-STK4046

PCB Layout Amplifier

Series Power Supply for Power Amplifier 200Watt By STK4050 been displayed in one image with a series of "Power Amplifier" 200Watt With STK4050 above. IC STK 4050 in this series there are several types on the market including STK4050II, STK4050V and STK4050.

And below is a list of STK ICs are used for a good quality amplifier.

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.
