ARC D-76
Information on the ARC D-76 is thin. What survives comes almost entirely from classified ads in period audio magazines. Those ads confirm that Audio Research made this model as a power amplifier in the late 1970s and early 1980s.
An ad in Audio (January 1979, p.133) listed a mint-condition D-76A amplifier for $750. A later classified in the same magazine (September 1981, p.89) offered a D-76G in excellent condition with its original carton for $625. That suggests at least two variants were sold, the D-76A and the D-76G. The "G" likely meant a gold-anodized front panel, since another ad from Audio (January 1979, p.133) described a "gold panel amp" paired with an SP3A-I preamp for $1,100. The "A" suffix may have meant a later revision or a standard silver-finish version.
Beyond these classified listings, no specifications, circuit details, power ratings or production run figures have been located.
