Compact power amplifier - fast high-end design

The battery-powered preamplifier published in our February 1997 issue must have made many of our readers long for a matching power amplifier. Odd as it may seem, it is almost two years ago that we last published a high-end power amplifier. This realization prompted the present compact power amplifier whose quality and layout match those of the preamplifier. It offers medium power output, is not overly complex and has a very high slew rate.
