This is a fully current and upgraded pair of M60's in excellent condition. They were upgraded by Atma-Sphere to full 3.1 status in January 2010 and carry one more year of the Atma-Sphere warranty extension to 2013. Serial numbers are #333.

This pair has TFTF V-Caps and PowerBoost options, no Caddock option. I am including a precision matched set of Russian output tubes, as well as a full spare set of generic ones that came with the amp. These tubes were carefully matched and burned in by an expert using a Transcendent Sound Tube Analyzer. The 6SN7's are a mix of Chinese tubes that Atma-Sphere uses and RCA's and Sylvania's allowing you to roll to taste in the 4 positions.

At my asking price I will also include the Speltz Zero autoformers shown in the pictures. They are a nice option with these amps if you intend to try different speakers and they are completely transparent.

I constructed 2 re-usable crates to ship these safely and the tubes will be carefully packed in a third box.
