Mark Levinson ML-3
Mark Levinson ML-3 amplifier
The Mark Levinson ML-3 was a 200 watt per channel dual monaural Class AB2 power amplifier that used toroidal transformers. Produced between 1979 and 1987, the ML-3 consisted of two electrically separate amplifiers in one chassis, hence the name "Dual Monaural". It also featured discrete circuit construction, no integrated circuits were incorporated in order to keep the signal pure. The design was by Thomas P. Colangelo.
The ML-3 constituted the archetype of an American highend, highpower amplifier.
