My Circuit

Amplifier circuit is very suitable for use in subwoofer speaker, because its strong. This circuit using ic, ic based on STK. to use it can be used on cars that use speakers or a subwoofer system in his car. 30 V supply voltage that has been rectified. Power output 20W mono. Part List : R1 = 100K R2 = 47R R3 = 100R R4 = 1R C1 = 220uF C2 = 100uF C3 = 100uF C5 = 10uF C6 = 1uF C7 = 1uF C8 = 1000uF C9 = 0.1uF IC = STK011 , STK015 , STK016

This chassis does not contain a specific Service mode. The Services and device setting can be made via Mode the Technical Assistance Factory. There is no program on TV Check method: Check the closed circuit to the tuner IC image encoder for detecting whether components defective. Or check if the resistance R117, R118, R203 and R204 has increased may cause the problem. No Good Picture or Dual Image Check the signal IF1 / IF2 to Q101 and relevant circuit. In this case the problem can be Q101 and / or SAW 101. No Picture or Color Correct • Check the circuit IC201 to RGB. • Check the welding IC and physical damage of the relevant circuit or check defective capacitors. Image with White Line Horizontal and Audio Check voltage supply of vertical IC301 and circuit relevant, and check the vertical sync signal IC201. Control Evil Operation Remote Check voltage at pin 64 of IC201. The normal value should be 5.15V. If correct check the welding connections front control panel. If it cannot be resol...
