McIntosh MC240

The McIntosh MC240 is one of the most revered vacuum tube amplifiers ever built, and it holds a special place in the company history as its first stereo tube power amplifier. Produced through the 1960s, it delivers 40 watts per channel in stereo or 80 watts in mono, using four 6L6GC output tubes and McIntosh Unity Coupled output transformers that give the amplifier its famously robust and musical character.

This is a classic vintage model, prized by collectors and listeners for its warm, dimensional sound and its legendary build quality. The chrome chassis, glowing tubes, and hand wired construction represent an era of American audio craftsmanship that continues to be sought after decades after the last unit left the factory.

Because the MC240 is a vintage component, condition and any restoration work vary from unit to unit, and buyers should evaluate each example on its own merits. When properly serviced, it remains a genuinely satisfying amplifier that pairs beautifully with efficient loudspeakers and period preamplifiers such as the McIntosh MX110.
