The Apt 1 Amplifier is a power amplifier for driving loudspeakers in a wide range of home music systems.

It provides a flexible complement to the Apt/Holman pre amplifier, but it is meant to allow an optimum match, without detrimental interactions, to any other possible system components.

The chosen design supplies the maximum useful power presently attainable without concessions in reliability or cost-effectiveness. It features novel approaches to protection circuitry and power supply design, as well as DC and AC stability.

It incorporates psycho acoustically optimized output monitoring indicators, switching for both bridging (monaural) operation and loudspeaker impedance matching. A power transformer with low external flux minimizes the amplifier's radiated hum field.

The flat, U-I lamination transformer has also allowed a convenient mechanical design, with a horizontal component layout making all parts accessible at the same time. Most servicing points can be reached by removing just the top cover and the two amplifier heat-sink modules.
