Integra R-77 (c. 1992)

Not much survives on the Integra R-77. The one solid reference is a receiver comparison in HiFI-Stereo (February 1992, p.58), which places it in the early-'90s A/V receiver market. The specs recorded there: 130 watts per channel into 4 ohms, power bandwidth 10-70,000 Hz, signal-to-noise ratio of 75 dB on phono and 95 dB on line, and tuner S/N of 75 dB. It came in a black anodized finish and cost $620.

That is the whole file. No owner's manual, service literature, or confirmed production dates have turned up, and the R-77's place in Integra's lineup is not documented. The page is short because the record is short.
