DIY audio amplifier circuit

DIY audio amplifier circuit:

This is a DIY audio amplifier circuit diagram. this is a mono diagram. This diagram can produce 150 watts using 2 transistors. 2sc5200 and 2sa1943 is a common transistor. We can also use another transistor in this circuit diagram. This diagram can produce strong watts because the transistor has a voltage in the emitter. and the sound quality is so good for the IC base driver section. here used 741 Ic. we can use 25-0-25 voltage to 50-0-50 voltage in this circuit diagram. and the ampere will be a maximum of 4 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 17.

This circuit doesn’t have speaker protection. here need a speaker protection circuit. here is the link to get the speaker protection circuit. Diagram is here

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.
