Electronics Help Care Amplifier circuit diagram
Audio amplifier circuit diagram USA technology:
This is an Audio amplifier circuit diagram, USA technology. This circuit board can produce 300 watts of output. It’s a mono diagram. A stereo needs a dual circuit board. Here, we can use a 25-0-25 voltage to an 80-0-80 voltage maximum. The best voltage is 50-0-50 volts and 6 amperes. We know that voltage X amperes= watts. So, 50 X 6= 300 watts. Voltage and ampere is the important to get a good output watts.
This circuit includes speaker protection. Every amplifier needs a speaker protection to save the speaker.

2sa1943 Polarity is PNP. The maximum collector power dissipation is 150 Watts. The maximum collector-base Voltage is 250 volts. Max Collector-Emitter Voltage is 250V. The Max Emitter-Base Voltage is 5V. The Maximum Collector Current is 17 amperes.
Details about 2SC5200
2sc5200 Polarity is NPN. The maximum collector power dissipation is 150 Watts. The maximum collector-base Voltage is 250 volts. Max Collector-Emitter Voltage is 250V. The Max Emitter-Base Voltage is 5V. The Maximum Collector Current is 17 amperes.
audio equalizer and amplifier:
This is an audio equalizer and amplifier circuit diagram. It’s one of the best circuit diagrams for the audio amplifier. This circuit has 4 adjustable vol. 1st one is for the volume. 2nd one is for the bass. 3rd one is for the mid-range. And the fourth one is for the trouble. This circuit runs with 12 volts only. It’s a stereo bass tone circuit. stereo audio graphic. dual channel, left channel, and right channel.
The transformer and the dc voltage section have to be the best to get the best output. The diode should bea minimum 10-ampere diode. capacitors 80 voltage 10000 mfd minimum 2 pieces.
Amplifier circuit using stk4231:
This is the amplifier circuit using stk4231. This is the stereo amplifier. we can use 25-0-25 voltage to 60-0-60 voltage. This amplifier can make 100+100 watts. We have to use the voltage according to the IC quality.
