DIY amplifier diagram:
this is a DIY amplifier diagram. This circuit can produce 100 watts using 35 voltage and 3 amperes. it’s a mono-circuit board. here, it needs dual voltage. positive negative and ground voltage. this circuit used 2 transistors 2sc5200 and 2sa1943. this pair of transistors can make 100 watts. one PNP another is an NPN transistor. here using 35-0-35 voltage and 3 amperes.
Details about 2SC5200
2sc5200 Polarity is NPN. Max Collector Power Dissipation is 150 Watts. The Max Collector-Base Voltage is 250 Voltage. Max Collector-Emitter Voltage is 250 Voltage. The Max Emitter-Base Voltage is 5 Voltage. Maximum Collector Current is 17 amperes.
Details about 2SA1943
2sa1943 Polarity is PNP. Max Collector Power Dissipation is 150 Watts. The Max Collector-Base Voltage is 250 Voltage. Max Collector-Emitter Voltage is 250 Voltage. The Max Emitter-Base Voltage is 5 Voltage. Maximum Collector Current is 17 amperes.
Here we can see maximum voltage is 250 voltage can throw the Emitter and Collector. and the Base can take 5 voltages. and the voltage ampere can take a maximum of 17ampere.
This is the Speaker protection circuit diagram. It can protect our Speaker from the burn. 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 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.
The diagram is here.
