Marantz 2330B receiver


The Marantz 2330B was manufactured from 1977-1980 and utilized state-of-the-art circuitry. Two direct-coupled power amplifiers on a single chassis, and a MOSFET front end to the sensitive FM tuner were just two of the features. The AM section of the tuner was highly selective. Construction quality was exceptional and the availability of comprehensive tone control and tape dubbing features made this a flexible and desirable unit.
The immaculate condition of this example, both internally and externally, suggests it has had little use, with no sign of wear. Sound quality is characterized by a clean, controlled low frequency ability with an open and detailed image. There is ample power for virtually all domestic requirements. Included in the sale is the optional Dolby FM module for use with the US model, and the original service and user manuals.
This unit is a US model requiring 110 volts, 50/60 Hz. An external step-down transformer can be utilized if it is to be used on 240 or 220 volt supply.
