A mid-tier AM/FM stereo receiver from Yamaha's early 1970s CR series. It puts out 22 watts per channel with low distortion and has an advanced tuner design.
Overview
It belongs to Yamaha's CR series of receivers, built during the early 1970s. It sits below the CR-800 and CR-1000, but it shares their core design approach, including low-noise reception and stable signal processing. It delivers 22 watts per channel into 8 ohms. It also has a microphone mixing circuit, loudness switch, and muting circuit, which many receivers at this level don't have.

Design
The tuner front end uses a low-noise FET. The IF amplifier section uses a solid-state filter, which is highly stable and can't go out of alignment. A high-gain monolithic IC with a differential amplifier handles the IF circuit. The MPX circuit uses a transistor switching method unique to Yamaha. The unit also has a muting circuit, a loudness switch, a selector switch for preamp and main amplifier, and a microphone mixing circuit.
Context
Yamaha built the CR-500 with its latest technology at the time, which made it a capable mid-range receiver in the early 1970s. It shares design and engineering principles with other models in the CR series, which became well-regarded for performance and reliability.
