There is perhaps no amplifier more iconic than the McIntosh 275. The original design from 1961, revived in '93, is now in it's sixth iteration, clad in a rust-resistant stainless steel chassis. The gold-plated terminals are ready for modern listening, and the unit is compatible with any standard IEC C13 power plug. This particular piece shows very few signs of use beyond a bit of swirling on the chassis. The silk-screened labeling on the tube sockets and terminals, which is common with these, and doesn't affect the performance at all. Electronically, we've added a new hand-matched set of Gold Lion output tubes, and has been carefully biased for critical listening.

- Liner Notes
Now in its sixth generation, the MC275 has many subtle enhancements from the previous releases that have greatly improved performance. Combined with the widest bandwidth McIntosh output transformer design, the MC275 features tauter bass control and thermally quiet circuit design. The result is pure music. This vacuum tube power amplifier has all the features to meet the needs of today’s music enthusiast, 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.
