**Mini Amplifier Circuit Homemade 5volt Power Supply C945 Transistor Sempal Circuit**

**Introduction**

A mini amplifier circuit is a simple electronic circuit that can be used to amplify the sound signal from a low-power source, such as a smartphone or computer, to a higher power level that can drive a speaker. A homemade 5volt power supply can be used to power the amplifier circuit. A C945 transistor is a common type of transistor that can be used in the amplifier circuit. A Sempal circuit is a type of audio amplifier circuit that is known for its simplicity and efficiency.

**Assembly**

To assemble the circuit, follow these steps:

1. Connect the C945 transistor to the circuit according to the circuit diagram.
2. Connect the 22uF / 16v capacitor to the circuit according to the circuit diagram.
3. Connect the to the circuit according to the circuit diagram.
4. Connect the 1k Ohms resistor to the circuit according to the circuit diagram.
5. Connect the heat sink to the C945 transistor.
6. Connect the 5v power supply to the circuit according to the circuit diagram.
7. Connect the speaker to the circuit according to the circuit diagram.

**Operation**

Once the circuit is assembled, it can be operated by connecting the 5v power supply to the circuit and the speaker to the circuit. The audio signal can be input to the circuit through the base of the C945 transistor. The amplifier circuit will amplify the audio signal and drive the speaker.

**Sempal Circuit**

A Sempal circuit is a type of audio amplifier circuit that is known for its simplicity and efficiency. It is a two-stage amplifier circuit that uses a single transistor in each stage. The first stage of the circuit is a voltage amplifier, which amplifies the voltage of the audio signal. The second stage of the circuit is a current amplifier, which amplifies the current of the audio signal. The Sempal circuit is a good choice for mini amplifier circuits because it is simple to build and does not require a lot of components.

**Conclusion**

This dissertation has described a simple mini amplifier circuit using a C945 transistor and a homemade 5volt power supply. The circuit is easy to build and can be used to amplify the sound signal from a low-power source to a higher power level that can drive a speaker. The Sempal circuit is a good choice for mini amplifier circuits because it is simple to build and does not require a lot of components.
