The circuit is a simple one transistor amplifier with amplification of about 30-40 dB (depends on transitor, temperature and voltage). The dynamic mic input is just a simple one transistor amplifier circuit with nothing special.

This is an amplifier design made by Nelson Pass publishes at 1977. This amplifier gives out 20 watts per channel into 8 ohms, 24 watts into 6 ohms, and 28 watts into 4 ohms. The amplifier is powered from 120V AC power.
