Sherwood AM-7040 (circa 1989)
Little is documented about the Sherwood AM-7040. Almost everything on record comes from a single period notice in HiFI-Stereo (July 1989, p.52). It listed the AM-7040 as a power amplifier rated for 200 watts per channel with 0.008% distortion from 20 to 20,000 Hz. The same note mentioned independent power transformers for each channel. That suggests Sherwood intended the AM-7040 for serious use, likely as the amplifier half of a separates system alongside a preamp/tuner from the same era.
Beyond that, there's nothing. No original price, no dimensions, no production run dates, no user reviews and no service documentation have surfaced in the Archive’s research. Whether the AM-7040 was a short-run model or simply one that escaped the usual paper trail is unclear.
