MV55 Vacuum Tube Power Amplifier

Introduced January, 1995

The MV55 continued the evolutionary development of our entry-level MV series amplifier, offering circuit refinements to the preceding MV52. The MV55 was offered in both ultralinear and triode configurations. Triode operation of the output stage achieves an exceptionally rich and musical sound, but at reduced power levels. Like the MV52, the MV55 features the use of polypropylene capacitors for the main power supply filter and reservoir - eliminating electrolytic capacitors from the main power supplies.

Features:

5-way binding post speaker connectors, one pair of inputs, two plate fuses, power switch.
