this amp is in very good condition all the pots and switchs are clean and work with no noise, one owner non smoker. I bought it in 2004 from official Macintosh dealer. All tubes are authentic. That item was under operation for about 80 hours. It is a very small term of operating for such an item. The fact is that I travel a lot and I was not at home for almost last two years. That item was not practically used. Totally I should say that it is in a wonderful condition except one little scratch. You can see it on my photoes. If you have any questions I will answer them with a great pleasure.
The MA2275 is the first McIntosh integrated amplifier to rely exclusively on vacuum tubes in all audio circuits. The new design combines classicvacuum tube audio performance with state of the art control technology.
A new ultra-low-noise preamp has been engineered for the MA2275. Old-fashioned point-to-point wiring, common in vacuum tube designs, has been replaced with glass epoxy printed circuit boards developed through modern computer-aided design techniques.
