Selling a Yamaha Natural Sound Stereo Receiver CR-820. Great working condition! Recently serviced by Pure Sound (https://www.puresoundbc.com/) in July - it's a beautiful piece. This is a classic upper mid-range receiver from the late 1970’s. It is the Yamaha CR-820 was on the market from around 1977 to 1979. It produced 55 watts per channel into 8 ohms and had low distortion ratings. In fact, while most manufacturers measured distortion at the rated output of the unit, Yamaha measured the distortion over a wide range of power output. They called this the Noise Distortion Clearance Range (NDCR). They trademarked the phrase ‘Real Life Rated’ because they measured noise and distortion at -20dB from the inputs all the way through to the speaker output as opposed to just measuring the amp section. They believed this would give a better indication of performance in a true listening environment. Power output: 55 watts per channel into 8Ω (stereo) Frequency response: 20Hz to 20kHz Total harmonic distortion: 0.02% Dimensions in Inches: 17.6 x 5.7 x 15.5 (w) x (h) x (d) Weight in lbs: 26.9 lbs
