Minimum_component_phono_amp_with_common_mode_volume_control

This circuit shows an LM380 as a phono amplifier with common-mode volume control.When in the full-volume position, the only source-loading impedance is the IC input impedance. This reduces to one-half the amplifier input impedance at the zero-volume position.
