Simplicity and purity of concept define the high-resolution dual-mono Walrus power amplifier, proudly hand-crafted in Denmark with precision engineered mechanical parts and electronic components selected for their fine sonic characteristics. Power 150W x 2.

The power amplifier is a dual mono Affair whose looks belie its weight. It is extremely heavy, due in part to no less than four large mains transformers and its substantial heat-sinking. Two pairs of loudspeaker outputs and again balanced or single ended options feature on the back panel along with the mains switch. Circuitry is basically Mos-fet, employing two pairs of high speed Toshiba output devices per channel, with minimal current feedback employed. Specified at 150 Watts per side into eight ohms, double the output is claimed into a four ohm load, promising good load tolerance.
