Atma-Sphere Music Systems M-60 MKII OTL Amplifiers

For sale, we have a beautiful pair of Atma-Sphere Music Systems M-60 MKII OTL Amplifiers. The units are in perfect working order, and they are in very good physical condition. There are some small blemishes, and nicks but there are no dents or deep scratches. The amps present themselves extremely well. Please see the many pictures in the listing for further details. There are also two internal pictures of one of the amps. (Both amps are identical inside) The amps were factory built, and are numbers matching with serial number 448.

The amps came from an eclectic steam punk designed 3 story apartment in NYC. The amps ran a pair of vintage JBL speakers. A Marantz Model 7 acted as the preamp, and a pair of Marantz Model 9's ran another set of JBL speakers. 

All tubes tested strong on our Amplitrex AT-1000 tube tester.

We don't have the original boxes for these units, but we take packaging and shipping seriously. We spare no expense and use heavy duty boxes, and polyethylene foam when boxing up our gear for shipping. The amps will  ship in two boxes. Each set of tubes will either ship with each amp, or all the tubes will ship together in a third box. We will make that determination when packing the amps.
