The Riviera Audio AFM70 operates in Class A and is capable of delivering 70 watts of power when operating on a load with a nominal resistance of 8 ohms. The pre-stage of the monoblock uses a vacuum lamp, and the output stage is built on semiconductors. Thus, a hybrid concept is implemented in the Riviera Audio AFM70.
