The current McIntosh MC275 is the sixth-generation version of the company’s enduring tube power amplifier. Four KT88 output tubes deliver 75 watts per channel in stereo through Unity Coupled Circuit output transformers. This is a current-production amplifier carrying a historic model name.
Why This Model Matters
The MC275 keeps its exposed-tube layout and polished chassis while incorporating modern protection and control features. Stereo operation supports 4-, 8-, or 16-ohm speakers; mono operation provides 150 watts into 2-, 4-, or 8-ohm loads. That choice makes it possible to start with one stereo amplifier or use a pair configured as monoblocks. Its transformers are central to matching the tube output stage to the connected loudspeakers.
