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.

 

MC275 Tube Power Amplifier Features

 

FULL POWER DELIVERY

The MC275 Series V delivers 75 watts per channel into 4, 8, and 16 Ohm speakers.

 

ULTRA LOW NOISE AND DISTORTION

Distortion-canceling properties of McIntosh’s Unity-Coupled circuit and

unique Output Transformer design yield much lower distortion and noise across

the entire 20-20,000Hz music range.

 

WIDE BANDWIDTH

McIntosh’s exclusive Output Circuit and Transformer designs ensure ultra-wide

frequency bandwidth.

 

MONOBLOCK

The two 75-watt channels may be combined into a single channel of 150 watts

into 2, 4 or 8-Ohm loads.

 

INVERTED CHASSIS

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.
