McIntosh MC275 2-Channel Vacuum Tube Amplifier

  • 75 Watts x 2 channels
  • Vacuum Tube Design

Description

Upon its initial release in 1961, the MC275 Vacuum Tube Amplifier became an instant favorite due to its ability to drive the power-hungry speakers of that time period with great power at low distortion levels. However, as transistors emerged and vacuum tubes became ‘old technology,’ the MC275 was discontinued in 1971. Thankfully, that is not where the story of the MC275 ends.

It came back into production as a special commemoration edition in 1993 to posthumously honor McIntosh co-founder and longtime president Gordon Gow. The reincarnated MC275 received incredibly high acclaim and earned its spot back in the product lineup. The overall storyline behind the MC275 and its history with McIntosh is exceptionally rich and it has been the driving force behind countless home audio systems for decades. It is hard to imagine McIntosh without the MC275.
