The MC275 is a legend. The most powerful of the vintage mac tubes, and arguably the most coveted. This is the fourth generation of the classic and well loved design. It's also the oldest with balanced inputs, modern speaker connections, and a stainless steel chassis, which makes this a particularly desirable model. This particular example is in excellent electronic and cosmetic condition, save for a tiny nick on the top of the center transformer. Without question, a must-have piece for any serious Mac collector.

- Liner Notes
Although the overall appearance of this generation of MC275 is similar to the previous ones, the most significant feature is the modern structure inside. The integrated and straightforward circuit board eliminates countless plug-in connectors and circuit boards. The new circuit board also designs electronic tube heat dissipation pipes to provide heat dissipation for the output operation of large electronic tubes and the additional external output operation of high voltage. In terms of appearance design, the base material is improved to corrosion-resistant polished stainless steel. Most importantly, McIntosh has improved the signal-to-noise ratio of the new generation MC275. Compared with other competing similar designs, the final result of all the improvements of the MC275 is a tube amplifier without any audible background noise.
