Sherwood S-7100A (c. 1972)

Almost everything known about the Sherwood S-7100A comes from Sherwood's own advertising in mid-1972, plus a brief editorial mention from the same season. It was a stereo receiver. Sherwood's ad opened by calling it "America's most popular receiver," then said the company had taken that model, improved it, and dropped the price. Surviving documentation is thin, but the period sources that exist are specific.

Sherwood's announcement ad ran in High Fidelity (June 1972, p.93) and HiFi/Stereo Review (June 1972, p.5). It listed what had changed: increased low-frequency RMS power, a broader power bandwidth, FM selectivity improved by 10 dB, a direct-coupled amplifier circuit, newly added ceramic filters, a restyled front panel, and a price $20 lower, at $199.95 including the walnut case. A short equipment entry in HiFi/Stereo Review (June 1972, p.59) added that the signal-strength tuning meter read full scale on most signals. It also said a metal cabinet with wood-grain finish was standard, with a real wooden cabinet available at extra cost.

Beyond that, the record gives out. No complete factory specification sheet has surfaced in the Archive's research. There is no confirmed power rating, distortion figure, dimensions or weight, and the production span is unconfirmed. What the S-7100A was, what it cost and how Sherwood positioned it is documented. The deeper technical story appears not to have survived.
