Electronics Help Care Amplifier circuit diagram This is the best audio equalizer circuit diagram for the amplifier. It’s a stereo bass tone circuit with a microphone. This circuit needs dual voltage, positive, negative, and ground voltage. 12-0-12 voltage. Every amplifier needs a pre-amplifier with a bass tone control. This circuit has bass, midrange, and treble.
This is the Amplifier Diagram circuit using STK4231. This amplifier makes 100watts+100watts audio output. STK4231+STK4211+STK4221 all IC diagrams are the same. Only the output watts are different. like stk 4141 series. Here needs dual voltage. We can use 15-0-15 voltage to 45-0-45 voltage, depending on the IC. Positive, negative, and ground voltage are needed in this circuit diagram. It’s a stereo audio diagram.
This is a 2.1 audio amplifier
The circuit diagram
DIY amplifier circuit using Tip41 and Tip42:
This is the DIY amplifier circuit using Tip41 and Tip42, and 2SC5200 and 2SA1943 transistors. It’s a mono amplifier circuit diagram. This circuit can make 150 watts of output. Minimum voltage should be 20-0-20. and the maximum is 50-0-50 voltage. and 3 ampers.
Driver circuit diagram for PNP and NPN transistors:
This is the driver circuit diagram for the PNP and NPN transistors. This circuit runs with positive, negative, and ground voltage. We can use 25-0-25 voltage to 60-0-60 voltage. 2sc5200 and 2sa1943 are the best transistors for this board. We can also use C5198 and A1941. We can use a minimum of one pair to 10 pairs of transistors.
