Commentary
Integrated stereo amplifier with improved performance by adopting IC.
Monolithic ICs are used in the IF amplifier stage of the FM tuner section and the MPX section.
The IC combines 40 transistors, 10 diodes, and 28 resistors to perform MPX demodulation, muting, blinking indicator lamps, and automatic switching between FM mono and stereo.
The amplifier has a center channel output terminal and a microphone input terminal.
