Sherwood 8900A

Little is documented about the Sherwood 8900A beyond its period advertising and a few lab-test quotes that Sherwood itself reprinted. The 8900A, sometimes written S-8900A, was the FM-only receiver in Sherwood's early-1970s pair. The S-7900A added AM. That distinction appears in Sherwood's own High Fidelity advertising (July 1973, p.27).

An Audio ad from April 1973 (p.31) quoted Hirsch-Houck Laboratories as saying the receiver's FM and audio sections left nothing to be desired, and that both delivered state-of-the-art performance for a receiver of the time. The same ad specified FM sensitivity of 2.7 µV for 50 dB signal-to-noise ratio. A later Sherwood campaign in HiFI-Stereo (February 1974, p.5) emphasized that the 8900A's appeal went deeper than its face. It reported superb sensitivity figures and test results where waveform clipping did not occur until 75 watts per channel. The power rating was evidently on the conservative side.
