700 mW amplifier with LM386 (CB966E)

This is one of the many versions of amplifiers with LM386. This was achieved in an old publication (1981). The circuit has volume control and can be powered by voltages from 6 to 9 V. The gain is fixed at 20 dB. The power supply must have excellent filtering and the input impedance is high. The circuit can be used on intercoms, radio receivers and other applications that require low power audio.
