For sale is a beautiful Yamaha receiver, with a rare black finish. These are supposed to be identical to the CR-420, but with black instead of silver. This one works perfectly and sounds superb! I have cleaned/dusted inside and out, and cleaned the pots and switches so they do not crackle. These specs are for the CR-420, which I took from hifiengine.com: Tuning range: FM, MW Power output: 22 watts per channel into 8Ω (stereo) Frequency response: 20Hz to 20kHz Total harmonic distortion: 0.05% Damping factor: 40 Input sensitivity: 2mV (MM), 120mV (line) Signal to noise ratio: 91dB (MM), 97dB (line) Output: 120mV (line) Speaker load impedance: 4Ω (minimum) Semiconductors: 2 x IC, 1 x FET, 53 x transistors, 25 x diodes, 5 x zener diodes, 3 x LED Dimensions: 451 x 161 x 324mm Weight: 9kg
