Electronics Help Care Amplifier circuit diagram This is a 200-watt audio amplifier circuit diagram. This circuit can make 200 watts. Here we can use a maximum 80-0-80 voltage. We are using here 60-0-60 voltage and 4 amperes. We know voltage X amp = Watts. The sunken transistor is one of the best transistors. Here, use 2sc2922 and 2sa1216. It’s a mono circuit diagram.
The transistor 2SC2922/2SA1216
The material of the transistor is Si
The polarity is NPN/PNP
The maximum Collector Power Dissipation is 200W.
The maximum Collector-Base Voltage is 180V.
The maximum Collector Current is 17A.
The max operating Junction Temperature is 150 °C.
The transition Frequency is 25 MHz.
The Current Transfer Ratio (hFE), MIN is 33.
This is the Speaker protection circuit diagram. It can protect our Speaker from burns. If the amplifier has any problem, then this circuit can save our soundbox. Normally, when the transistor makes a short circuit, the voltage comes out from the speaker output line, and then this circuit protects that voltage. This circuit should not allow any direct voltage to be sent to the speaker. This circuit is very important for protecting the speaker.
This is a 2.1 audio amplifier circuit diagram, 25+50+25 watts. This circuit runs with a minimum 12-0-12 voltage to a maximum 25-0-25 voltage. But the best voltage is 15-0-15 to 20-0-20 voltage. This circuit has a stereo input for the surround output. The surround per channel got 25 watts. The left channel is 25 watts and the right channel is 25 watts. The bass output is 50 watts.
