Mono Preamp with Small Transformer and Two Transistors

The microphone preamplifier described here is a ‘hybrid’ passive / active. A small transformer input provides a small contribution to the gain of all (about 10 dB), and a transistor provides the additional gain (35 dB) for normal use with a small dynamic microphone. About 40 kHz bandwidth, small and simple installation that requires little space.
