Marantz SQA-1

Marantz's Model 2440 adaptor/amplifier was rated at 40 watts continuous RMS power (High Fidelity, January 1973, p.17). The Model 4100 control amplifier offered 120 watts RMS in stereo (Hi-Fi Stereo, December 1972, p.37). The SQA-1 itself is not documented in any period source. Period directories, magazine archives, service literature and collector databases have no listing, no photograph, no specification and no mention of this model number. The fact sheet for this entry came up empty in every category: identity, design, history, market context and reception.
