The MC-40 was the mono version of McIntosh's highly popular stereo power amplifier, the MC-240 and similar to the MC-75 except for output power (40-watts versus 75-watts). Features included the by-now-standard chrome chassis and large, potted transformers. An octal output socket was provided for all impedances (4, 8, 16, 125, 150 and 600) and voltages with a barrier strip for 4, 8 and 16 outputs.

Frequency response was quoted as being from 20Hz to 20kHz (+0 -0.1dB) and distortion 0.5% at rated output (20Hz to 20kHz).

Priced when new: $159. Today expect to at least $600 for a nice, clean working example and up to $900 for mint condition units.
