Bought this on ebay a couple years ago. Essentially the power section of a D-180 or Bass 400. I need to sell extra equipment to pay bills so am letting this go. Its in good shape for the age and works great. There are some paint dots on it that I didn't try to remove but probably could easily. Mesa Boogie M 190 Tube Differential Feedback Amplifier.
