12v Transistor Amplifier Circuit Diagram. Electrolytic capacitors voltage rating must be according to the supply voltage you use. A simple transistor amplifier circuit diagram and schematic which can be used as a 12 watts audio transistor amplifierAn op amp IC is used to produce the gain required.
The easy circuit using a 12V supply. Electrolytic capacitors voltage rating must be according to the supply voltage you use. You may use others such as 2SC1815 or 2SC945 or 2SC828 etc.
Only a single IC gives a power of 2 watts max on 8 ohms.
It can extend the signal strength max 2V. Any op amp which can be operated from a 12V dual supply can be used instead of uA 741. How to Build a Voltage Amplifier Circuit with a Transistor. The circuit build based on ordinary tone control circuit using two low cost transistors FCS9014 in each channel so there are will be four transistors in this 12v stereo tone control.
