Electronics Help Care Amplifier circuit diagram
Amplifier circuit board using 2SC5200 and 2SA1943:
This is an Amplifier circuit board using 2SC5200 and 2SA1943. It’s a mono diagram. We can get 200 watts using this diagram. This diagram needs dual voltage. positive, negative, and ground voltages. we can use 25-0-25 volt to 50-0-50 voltage and 5 amperes. Voltage X Amperes = Watts. A 50X5=250 watts transformer needs to get 200 watts of output.
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.
Details about 2SA1943
2sa1943 Polarity is PNP. Max 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.
This is the Speaker protection circuit diagram. It can protect our Speaker from the burn. If the amplifier has any problems, this circuit can save our soundbox. Normally, when the transistor makes a short circuit, the voltage comes out from the speaker output line, and this circuit protects that voltage. This circuit should not allow direct voltage to be sent to the speaker. This circuit is essential for protecting the speaker.
Amplifier circuit using STK035:
This is an amplifier circuit using STK035. This diagram can produce a 35W+35W output with an 8-ohm load. It’s a stereo audio circuit diagram. The voltage should be a minimum of 25-0-25 and a maximum of 70-0-70. Dual IC for dual side.
We like deep and powerful low-frequency sound; a bass booster circuit is the perfect solution. A bass booster enhances low-frequency audio before they reach the amplifier, making music sound so dynamic.
