To complement the 60 watt mosfet audio amplifier a high quality preamplifier design was the output of the main module will be connected to a 22k log. A preamplifier circuit with a very low noise characteristic can be built by simply combining a fet transistor with a bipolar one. It is probably the one of the easiest audio amplifiers to build.
This circuit is little hard to built.
High fidelity preamplifier circuit diagram. Electret microphone preamplifier wiring diagram and test. High fidelity preamplifier circuit diagram. The ic requires very few external components, has very low noise and has a wide power supply voltage range.
