The third schematic of an audio preamplifier is presented in figure 7. It has the advantage of being an adjustable-gain amplifier, and its absolute voltage gain may vary from about 10 to 33. The gain can be adjusted from R4 potentiometer. Figure 7. The 3rd electronic schematic of a simple preamplifier. In this schematic, the base of the second ...

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.

This is a high gain preamplifier that is suitable for use where a lot of gain is required - to drive a power amplifier that needs plenty of gain or perhaps for use with instruments, like a guitar or microphone. If you need less gain, take a look at the RCA 12AU7 / ECC82 Cathode Follower Tube Preamp Schematic which has a gain of about 8.
