Stereo power amplifier "Limited Edition".

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 and low distortion levels. However, with the emergence of transistors and the gradual abandonment of vacuum tubes, the MC275 was discontinued in 1971. Fortunately, the story of the MC275 does not end there. It returned to production as a special commemorative edition in 1993 to posthumously honor McIntosh co-founder and longtime president Gordon Gow. The reincarnated MC275 received immense acclaim and earned its place back in the product lineup. The overall story behind the MC275 and its connection with McIntosh is extremely rich, and it has been the driving force behind countless home audio systems for decades. It's hard to imagine McIntosh without the MC275.

Now in its sixth generation, the MC275 features many subtle improvements over previous versions that have significantly enhanced performance. Combined with McIntosh's wider bandwidth output transformer design, the MC275 offers tighter bass control and a thermally quiet circuit design. The result is pure music. This vacuum tube amplifier has all the features to meet the needs of today’s music enthusiasts, while preserving the qualities that have made the MC275 the most revered McIntosh vacuum tube amplifier.

The MC275 can be used in either stereo or mono mode. When used as a stereo amplifier, it will deliver 75 watts per channel to 4, 8, or 16-ohm speakers; in mono mode, it will output 150 watts to a single speaker with an impedance of 2, 4, or 8 ohms. The MC275's full power can be delivered regardless of the speaker impedance thanks to our patented Unity Coupled Circuit output transformer technology – the same technology McIntosh was founded on in 1949. The two Unity Coupled Circuit output transformers are located next to the power transformer.

Four KT88 vacuum tubes power the output section, while four 12AT7 and three 12AX7A smaller tubes are used for the input, voltage, and driver amplifiers. The MC275 offers both balanced and unbalanced inputs to connect to your preamplifier and home audio system. It comes with our fuse-less Sentry Monitor™ short-circuit protection, which disengages the output stage before the current exceeds safe operating levels and resets automatically when operating conditions return to normal. Our patented gold-plated Solid Cinch™ speaker binding posts ensure the best connection to all speaker cables.

The seven small tubes are LED-illuminated to indicate the amplifier's functional status: upon power-up, they sequentially glow amber for a few seconds, then all turn green to signify system readiness. In the rare case of an output tube failure, the small tube(s) in front of it will turn red to notify you of the issue. An input and output for our Power Control technology allow other connected McIntosh components, such as preamplifiers, CD players, turntables, or media streamers, to automatically turn on and off.
