Available for sale a Brand new (open box) McIntosh MC275 with everything included.
It is Brand New and never used before.
This tube power amplifier is 220-240v. It 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 tube amplifier.  This sixth generation MC275 has many subtle enhancements from the previous release that greatly improve pe​rformance. 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.   McIntosh patented, gold plated, speaker binding posts assure the best connection to all speaker cables, while high quality balanced and unbalanced input connectors enhance signal transfer from the connected preamplifier.   The seven small tubes are LED illuminated to indicate the amplifiers functional status: upon power up, they sequentially glow amber for a few seconds and then all turn green to signify system readiness (see below). In the rare case of an output tube failure, the small tubes in front of it will turn red to notify you of the problem. Power Control is used to remotely control tube illumination from a McIntosh preamplifier
The MC275's transformers utilize the same "unity-coupled circuit" that McIntosh invented in 1947. The two primary strands—one connected through the power supply to the plate and cathode of one of the output tubes, the other connected in the same manner to the other tube—are tightly wound together, turn for turn, for complete magnetic coupling. This creates almost instantaneous local feedback, which is said to reduce distortion. In the original and all subsequent versions of the MC275, including this one, a third winding is connected to the plates of the cathode follower driver; this was said to extend the ultra-low distortion over a much greater bandwidth, especially into the high frequencies.
