Simple Preamplifier Circuit using BC547 Transistor
https://circuits-diy.com/simple-preamplifier-circuit-using-bc547-transistor/
There are many amplifiers available like using transistor, op-amp, transformer-based, etc. Sometimes we use the pre-amplifier circuit to amplify the weak signals for detection So in this tutorial, we will build a Simple Preamplifier Circuit using NPN transistor BC547.

The circuit schematic for the first audio preamplifier is presented in fig 1. The preamplifier uses only two NPN transistors. Both transistors are BC172. You may also use BC547 instead, or another equivalent type as well. Figure 1. The first simple preamplifier circuit The technical features of first preamplifier are summarized as follows:

1) Preamplifier using two Transistors. A simple pre-amplifier circuit can be very easily built by assembling a couple of transistors and some resistors as shown in the following figure: The circuit is a simple two transistor pre-amplifier using a feedback loop for enhancing the amplification. Any music as we know is in the form of a ...
The Single NPN Transistor Audio Preamp - HACK A WEEK
http://hackaweek.com/hacks/the-single-npn-transistor-audio-preamp/
The Single NPN Transistor Audio Preamp. Here’s a great little project that goes well with the LM386 audio amp. It’s a good first time transistor project because it’s simple and demonstrates the common emitter class A amplifier circuit with only six components in the signal path. A “Class A Amplifier” operation is one where the ...

Then, the audio signal coupling to through the C1 and R1 to amplifies by transistor-Q1. Which the Q1 is a first Preamplifier to increase a little signal up. Before sending it to Q2. Next, the Q2 is connected to the emitter follower circuit. Its function is a driver amplifier to boost up a signal from the preamplifier section.

The circuit of simple preamplifier is designed using a single low power amplifier transistor and is configured in common emitter mode. The input signal is given to the base of transistor T 1 through capacitor C 1. Capacitor C 1 is a coupling capacitor to couple the input signal to the base-to emitter terminals of the transistor.

Try making an amplifer were the voltage across the collector resistor is 3 volts, the voltage across the emitter resistor is 3 volts and the collector-emitter voltage of the transistor is 6 volts with the battery 12 volts. Choose all four resistors so the amplifier is at the operating point. Measure Iband ICand make sure they are not zero.
