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. Both balanced and single ended inputs are supported. The mirror polished stainless steel and black chassis with die cast nameplate is presented here just as it was in the original 1961 model.
McIntosh MC275 Vacuum Tube Amplifier Features
The MC275 Series IV delivers 75 watts per channel into 4, 8, and 16 Ohm speakers.
Ultra low noise and distortion.
Distortion-canceling McIntosh Unity-Coupled circuit and unique Output Transformer design yield much lower distortion and noise across the entire 20-20,000Hz music range.
McIntosh’s exclusive Output Circuit and Transformer designs ensure ultra-wide frequency bandwidth.
The two 75-watt channels may be combined into a single channel of 150 watts into 2, 4 or 8-Ohm loads.
Heat producing tubes are located on top of the chassis, under a protective cage, while other circuits are shielded within the polished Stainless Steel Chassis.
RCA and Balanced XLR Input Jacks.
Ceramic Tube Sockets with Gold-Plated Pins.
Stereo/Mono Switch.
