Mark Levinson ML-3

The Mark Levinson ML-3 is a 200 watt per channel dual monaural[1] Class AB2 power amplifier that uses two Avel Lindberg toroidal transformers in its powersupply and four huge Sprague Series 36DX, 36.000uF, 100 Volt capacitors.

Produced between 1979 and 1987, the ML-3 consisted of two electrically separate amplifiers in one chassis, hence the name "Dual Monaural".

The first version had smaller Callins 18.000uF main filtercaps and no decoupling for the driver stage.

The second version added 1.700uF decoupling caps for the driver stage and WW Fischer Camac system in- and output connectors.

The latest version got an anti buzz circuit, double AC fuseholders and two dampingswitches (for each channel) at the back for optimizing output impedance of the amplifier towards the used loudspeaker.
