Introduced October 1980, 45A in March 1982, 45A-1 in January 1983
The MV45 vacuum tube power amplifier was designed for audiophiles who had moderately efficient speaker systems and for less efficient speakers systems if high listening levels were not required. A single pair of EL34 output tubes produced 45 watts per channel. The MV45 employed metal film resistors and polyester and silvered mica capacitors throughout the circuitry.
The MV45A revision upgraded the mylar capacitors to polypropylene capacitors. The MV45A-1 upgrade incorporated circuit revisions to reduce the impedance of the regulated power supplies for the voltage amplifier and inverter stages.
Features: 4, 8, 16 ohm speaker taps (screw type), one pair of inputs, power switch. Rack mount panel optional.
