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:

As the name suggests a preamplifier circuit pre-amplifies a very small signal to some specified level that can be further amplified by an attached power amplifier circuit. It basically acts like a buffer stage between the input small signal source and a power amplifier.

audio preamplifiers A preamplifier circuit with a very low noise characteristic can be built by simply combining a FET transistor with a bipolar one. The input impedance of the preamp circuit is almost the same as the gate impedance of the FET transistor (around 1MΩ) The output impedance at the other end is about 1KΩ.

Sometimes we use a Preamp Circuit in circuits for pre-amplification of weak signal when the audio source sound level is too low. Pre-amlification of low level signals is necessary before feeding them into a power source, for clear and noiseless sound. In this project, we will build a Simple Preamplifier Circuit using NPN transistor BC547.

Universal Preamplifier using 741 This is a mono preamplifier circuit. Which it can use with various inputs. For example, microphone, tuner, CD and AUX. In the circuit above, IC741 is set into inverting amplifier mode. When a signal flows to AF in through C1 and R1 to pin 2 of IC1. Then, the signal goes out of pin 6. R4 acts as feedback resistors.
