How to make a simple amplifier using 04 single transistor 13003 making Circuit Diagram Read first for beginners: How transistor work. Power Amplifier OTL using AC176+AC126. Mr. Somsak is my friend who likes to make a power amplifier so much. but he does not well electronic man. I so introduce he needs to make an easy project before. This circuit is a simple power amplifier OTL that mini watt output but is an older circuit. Now the transistor will give a great result. Here I used 1k Resistor for removing lower Frequencies. This will increase the sound quality of the speaker. When the Base of the transistors gets to the low amplitude signal then the base became active in this state. For this reason, the Transistor became a conductive Collector to Emitter.
This single transistor amplifier circuit is very simple to make. It employs the Simple BC547 Transistor. 2.2K Resistor is the base resistor for this transistor., provides an audio signal at the base of the transistor which allows to flow of the current between collector and emitter. Capacitorwired in this circuit isolates the base of the The transistor is in the forwarding stage when the input is provided at the base of its base. During the whole audio cycle that is provided to the transistor, it generates the maximum amplitude at the output side. For Condenser Microphone Input signal. This Simple Single Transistor Audio Amplifier circuit is a simplistic preamplifier circuit.
7 simple amplifier circuit diagram using transistor
First place transistor on breadboard . Insert resistor at pin 1 and 2 of transistor . Insert positive terminal of capacitor at pin1 of transistor . Insert one wire of 3.5 mm jack at negative terminal of capacitor. Insert remain wire of 3.5 mm jack at pin3. Insert one wire of speaker at pin2 . Connect remain wire of speaker to +5v supply .
This simple basic audio amplifier circuit first receives a low input audio input signal of any kind with the help of a 3.5mm Jack. This audio signal is then given to the base of the transistor through the 100uf capacitor. The capacitor triggers the NPN transistor therefore the transistor starts operating. The transistor magnifies the audio signal.
How to Make a Homemade Amplifier? Circuit Diagram
A light bulb works as a powerful resistor. It is difficult to find for example a 21W resistor, that is why I use a lightbulb instead. You can use 1W - 40W light bulb. The more powerful light bulb you use the more powerful amplifier you'll get. But for a powerful amplifier you will need a powerful power source as well, and a big heatsink.
