About the MC50
The McIntosh MC50 is a vintage solid state monaural power amplifier manufactured from 1969 to 1978, delivering 50 watts continuous (RMS) power output into 4, 8, or 16 ohm speaker loads with a frequency response of 20 Hz to 20 kHz and maximum total harmonic distortion of 0.25%. It uses a McIntosh autoformer output stage for optimal matching to 4, 8, and 16 ohm speakers, and includes a front-panel gain control for adjusting input sensitivity. The MC50 provides a damping factor of 17, input sensitivity of 0.5 volts, input impedance of approximately 200,000 ohms, and a signal-to-noise ratio of 90 dB. The compact chassis measures about 5.5 inches high, 12.5 inches deep, and 8 inches wide, and weighs roughly 20 pounds. Known for its reliability, low distortion, and clear sound reproduction, the MC50 remains a respected classic mono power amplifier among audiophiles and vintage McIntosh enthusiasts.
