YAMAHA CR-700
Price unknown (around 1971)
Commentary
A stereo receiver developed using Yamaha's latest technology.
A low-noise FET is used for the front end of the tuner section, a solid state filter with high stability and no misalignment is used for the IF amplifier section, and a high-gain monolithic IC with a differential amplifier is used for the IF circuit.
The MPX circuit uses a transistor switching method unique to Yamaha.
An auto-touch switch is used for the tuning knob, and the AFC is automatically turned OFF when the tuning knob is touched.
Equipped with a muting circuit.
All stages are directly connected to the OCL amplifier, and the characteristics are improved by eliminating the coupling capacitor.
Equipped with a loudness switch and high-low filter.
Equipped with a selector switch for the preamp and main amplifier.
Equipped with a microphone mixing circuit.
