Brief into MC275 Vacuum Tube Amplifier

The Amplifiers are known for the powerful and detailed sound stage. The vacuum tube amplifier is one of them. The legendary Unity Coupled Output of Transformer uses two plates and here the second one is used for cathodes. The plate does not draw all the output power from the it but this Unity Coupled design is used to draw from both the plates and the cathodes. It helps to reduce the distortion which is a big problem in the tube designs. By the mixture of secondary windings amongst the primaries its coupling is very much improved and which helps to improve the power bandwidth.

The MC275 Vacuum Tube Amplifiers were designed and engineered by McIntosh co-founder Sidney Corderman and the McIntosh Engineering Team. The MC275 uses balanced or single ended inputs. It is configured for 75 watt per channel stereo, and MC275 can power 4, 8, or 16-ohm loads. It delivers 150 watts into 2, 4, or 8-ohm loads.
