The C22 Preamplifier was originally in production from 1963 to 1972. A commemorative Frank McIntosh version was designed and in production from 1995 to 1998. The C22 returns with updated circuitry for the 60th anniversary. The MC75 Monoblock Amplifier, originally in production from 1961 to 1970, returns as the amplification companion to the C22. These 60th anniversary models are available as a set and production is limited. McIntosh continuously incorporates performance and reliability improvements into each new product design to maintain their lead in technical superiority. Both the C22 and MC75 reflect today’s advanced tube design and updated circuitry yet the classic cosmetics remain similar to the original design.
C22 and MC75 Features
C22 Tube Preamplifier
Introduced in 1963, the McIntosh C22 Tube Preamplifier ushered in the era of audio preamplifier as “control center”. Designed to function as a superb line stage, phono preamplifier, equalizer and input switch, the C22 raised the bar for competing preamplifiers, and forged a standard of features and flexibility for future McIntosh preamplifier designs that endures to this day.
The 60th Anniversary Limited Edition C22 Tube Preamplifier recreates the look and feel of the original C22 with its backlit glass and brushed anodized aluminum frontpanel, and sees the addition of a number of circuit enhancements that bring the design current with recent McIntosh preamplifier specifications. Balanced inputs and outputs are provided to insure optimum performance with fine quality source components, while the addition of a moving coil and moving magnet phono amplifier guarantees compatibility with the widest range of phono cartridges. Blessed with modern materials and manufacturing methods, all signal switching in the C22 is done with electromagnetic switches driven by Digital Logic. Lastly, in what is perhaps the most striking nod to contemporary technology, the Limited Edition C22 comes complete with an IR remote control.
MC75 Tube Monoblock Power Amplifier
The year is 1961; McIntosh Laboratory has introduced the MC275 75 watt per channel stereo amplifier and its 75 watt monaural counterpart, the MC75. Just three years earlier the BBC had begun regular broadcasts in stereo sound, and demand for stereo playback
systems was growing. Still, recognizing the value of monoblock amplifiers to the ultimate quality of audio playback, McIntosh releases
the MC75. Here is early proof of our penchant for pushing the limits of performance in an effort to provide our customers with the very
best solutions in audio.
In recognition of our 60th anniversary, it is with great pride that we offer this Limited Edition MC75 amplifier. Largely true to the original design, the 60th Anniversary Edition MC75 offers many circuit updates that improve reliability while retaining the alluring sonic character of the original. Among the updates is a custom application of the patented Sentry Monitor short circuit protection. Balanced inputs and outputs are added to make this amplifier ready for today’s digital sources. The MC75 develops 75 watts into 2, 4, or 8 ohms. A brilliant, triple-polished gold color titanium stainless steel chassis takes the place of chrome plating for a stunning appearance that lasts a lifetime.
