Revox - A50 - A76 Hi-fi set - Multiple models

The Revox A50 was launched in 1968, marking the first time the Swiss brand offered the general public a complete hi-fi system. It introduced the integrated amplifier A50, the tuner A76, the reel-to-reel recorder A77, and a range of speakers in the 46 series, which included five models to build a very high-end (and very expensive) hi-fi setup.

The Revox A50 features a front panel entirely in aluminum, with a removable strip that allows access to the input level adjustments for line and phono inputs. With the brand’s traditional knobs and the elegant wooden cabinet, the A50 has an unmistakably ’70s look, combining style and functionality in a discreet and refined package.

With 2 x 40 watts per channel, it easily drives many modern loudspeakers, offering excellent dynamics and that neutrality typical of Swiss amplifiers: a real joy for music lovers.
