Here's a fantastic McIntosh MC275 MK1 amplifier.
The power supply caps were replaced and the amplifier is performing flawlessly. I installed a new cord for safety. The chassis is original with patina and a few flaws. The bottom cover is free from rust and corrosion. The transformers still have their original decals and the paint is original. There are 2 spots on the chassis towards the middle with some scratches. I'd rate the exterior cosmetics as 8/10 or so. As far as older McIntosh amps go, this is nicer than most but not perfect. The tubes are good quality and will be shipped separately from the amplifier.
The sonic performance is very impressive. I've played this amp for around 20-30 hours with various preamps and speaker combinations. It has performed flawlessly throughout all configurations. The clarity and power is just awesome. There is no hum above what I would consider to be superficial.
I am very fortunate to have a small collection of audio equipment to enjoy. I think this MC275 is one of my all-time favorites. I'm certain the new owner will love it. Price includes professional shipping to the 48 states. Please let me know if you have any questions. Thanks! -Bob
