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.
