Description :
Renown to be the top and best tube amplifier McIntosh has ever built during that time. An object of desire cherished by music lovers around the world, the MC275 was designed and engineered in 1961 by McIntosh co-founder Sidney Corderman and the McIntosh Engineering Team. Based upon the extraordinary Unity Coupled Circuit, the MC275 has a lush sound that presents a powerful and detailed soundstage. The MC275 develops 75 watts per channel into 2, 4 or 8 ohm loads, or 150 watts in bridged mono mode. The mirror polished stainless steel and black chassis with die cast nameplate is presented here just as it was in the original 1961 model.
