how to make an amplifier at home easy:
how to make an amplifier at home easy. this circuit diagram for the amplifier. it’s an easy circuit diagram. but this is the theory for making an amplifier. this circuit diagram is for learning people. Those who want to know how to make amplifiers can try this circuit diagram. here use two transistors some resistors and one capacitor only.
This circuit runs from 6 to 12 volts using a 2n2222 transistor. All resistors are 1/2 watts. It’s a mono-circuit diagram. speaker output capacitor value is 1000mfd 25voltage. input capacitor we can use 0.47uf to 2.2uf 50 voltage.
This circuit doesn’t have speaker protection. here, we 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.
