In early 1984, Elektor magazine beat the competition hands-down by publishing the design of a then-revolutionary MOSFET ampliﬁer. Even now, this ampliﬁer enjoys an enthusiastic following. In response to many requests, we have brought the design up to date and given some attention to improved reliability and operating safety. The output power is 90 watts into 8 ohms or 135 watts into 4 ohms, which should leave little to be desired for most users.
