Audio Research 76-A
Little is documented about the Audio Research 76-A. The archive holds no manual, no full review, and no confirmed production dates. What the record shows is a handful of classified listings in Audio magazine from 1979 to 1988. They establish the basics: this was an amplifier, written in period ads as either D-76A or D76A.
An Audio classified (January 1979, p.133) offered a mint D-76A at $750. Another entry in the same issue paired a gold-panel D76A with an SP3AI preamp at $1,100. A July 1980 listing in Audio (July 1980, p.84) still asked $750, alongside an EC-2 crossover with rack-mount panel. By January 1988 (p.167), a seller described a D76A that had been recently retubed, a strong hint that the 76-A is a vacuum-tube design. He offered it in trade for a McIntosh MR78 tuner.
That is nearly all the documentation that survives. Known specifics from those classified ads:
- Tube amplifier (suggested by the 1988 mention of recent retubing)
- Gold panel finish noted in a 1979 listing
- Used prices: $750 in 1979 and 1980; $1,100 with an SP3AI preamp in 1979
