C1815 Transistor Amplifier Circuit Diagram. C1815 is a bjt type npn transistor. Pre amplifier circuit diagram using a transistor.
The complete circuit diagram for dual channel pre amplifier consists of two mono circuits combined to form one stereo circuit as shown in the image below. The amplifier output power may differ according to the transistor rating. As you can see the left channel audio and right channel audio feeds through two parts of the circuit and i have used 3 pieces of single channel 47k potentiometers for controlling.
It is used for audio amplification and high frequency oscillator osc.
As you can see the left channel audio and right channel audio feeds through two parts of the circuit and i have used 3 pieces of single channel 47k potentiometers for controlling. If you do not have this one 2sd30. The amplifier output power may differ according to the transistor rating. C1815 is a widely used transistor it is used in commercial and educational projects.
