Amp is sold.
For sale is a pair of Atma-Sphere M-50 monoblocks in Champagne Gold which were upgraded by Ralph to M-60 Mk 3.1 before I bought them. Original 12AU7/12AT7 input/driver stage was replaced with current 4x6SN7 configuration. The update included wiring, choke, Hexfred diodes and latest resistor change. I liked them so much I had Ralph upgrade them again to the latest 3.3 version including the V-Cap option.
The amps are in good cosmetic and great operating condition. Rated 7/10 because of age and multiple ownership. I very much liked the rack mount chassis as I actually rack mounted them for a while. 45 (yes, 45, almost 3 sets) 6AS7 tubes included which are all tested and are a mix of Soviet, GE, RCA, and Chatham. 8 tested 6SN7 tubes also included. Shorting plugs are included if you want to run them single ended. Amps will be shipped in two boxes for safe transit, with tubes sent in separate box. The amplifiers come with generic power cords. PayPal fees included in asking price.
