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:

The amplifier is an electronic circuit or device used for amplification and primarily used in the reproduction of sound and mainly in our electronics industry. 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 …

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.
