An object of desire cherished by music lovers around the world, the MC275 is hard to beat.
Our amplifiers have a lush sound that presents a powerful and detailed soundstage. Their legendary Unity Coupled Output Transformer uses two bifilar wound primaries - one for the plates, as is normal, and a second for the cathodes. Instead of drawing all the output power from the plates, as many other designs do, the Unity Coupled design draws from both the plates and the cathodes. This greatly reduces the output distortion - always a problem in tube designs. By mixing the secondary windings in amongst the primaries, coupling is improved -flattening the output frequency response and improving the power bandwidth.
The MC275 Vacuum Tube Amplifier was designed and engineered by McIntosh co-founder Sidney Corderman and the McIntosh Engineering Team. The MC275 uses balanced or single ended inputs and a compliment of (3) 12AX7A, (4) 12AT7 and either (4) KT-88s or 6550 tubes. Configured for 75 watt per channel stereo, the MC275 can power 4, 8, or 16-ohm loads. As a bridged mono amp it delivers 150 watts into 2, 4, or 8-ohm loads. THD is below 0.5% from 20 Hz to 20KHz at all times.
