Sherwood S-7210 (mid-1970s)

The Sherwood S-7210 is a stereo receiver. An original S-7210 Receiver Service Manual survives in the collector market, and that confirms it. The documented record beyond that is thin, but the period sources that exist give it a clear spot: it was Sherwood's mid-priced receiver in the 1974-1975 lineup.

Sherwood's own "What price glory?" advertising put the S-7210 in the middle of a three-model receiver range at $299.95. The company claimed 31+31 watts per channel into 8 ohms at 1 kHz (26+26 watts from 40-20,000 Hz), 0.8% distortion at rated output, and 1.9 µV FM sensitivity (IHF) (Audio, October 1974, p.127; High Fidelity, September 1974, p.47). Audio's equipment profile a few months later (July 1975, p.34) described a front panel typical of the period. A flywheel-coupled tuning knob sits at the right. A master volume control calibrated in dB doubles as the power switch. Rotary controls run along the lower section, including a program selector.

Known specs, from Sherwood's own 1974 advertising:

Original price: $299.95
Power: 31 + 31 W/ch into 8 ohms at 1 kHz; 26 + 26 W/ch, 40–20,000 Hz
Distortion: 0.8% at rated output
FM sensitivity: 1.9 µV (IHF)

What isn't documented: no complete factory specification sheet, no confirmed production span, and no design or circuit details have surfaced in the Archive's research. The survival of the service manual — offered secondhand by Vintage Audio Store — is itself evidence of how the model is remembered today: as a serviceable, mid-line 1970s Sherwood receiver that collectors are still willing to maintain.
