This is one of Sherwood’s upper end models the Sherwood S-7100. The Sherwood company was founded in 1953 by Ed Miller and John snow. Their primary products were amplifiers, tuners and receivers though they also had a speaker line. In 1961 Sherwood participated in the world’s first stereo radio broadcast which utilized Sherwood equipment. The S-7100 is one of Sherwood’s later solid state models though it is said to have a warm tube like sound to it.
The S-7100 puts out roughly 18 watts per channel though I have seen other specs show anywhere from 14 to 22 watts per channel. Sherwood was known for their exceptional FM tuners and the S-7100 is no exception.
The Sherwood company produced the first completely solid state receiver in 1967 so they were at the forefront of the new technology of the time. While most of their line was originally manufactured in the U.S. they moved production to Korea in 1978.
The build quality of the early Sherwood receivers was exceptional and their performance matched that of the more well known brands of the time.
The S-7100 utilizes a plastic switch inside the power / volume knob that can decay quickly if solvent is used to clean it. So, if you do intend to clean the switch be sure to use a cleaner that does not have solvents in it.
Sherwood also sold the S-7100A which was slightly different than the S-7100 though you wouldn’t really notice it from the outside of the unit. As you can see the S-7100A below is essentially exactly the same on the front as the S-7100 with the exception of the knobs. The knobs on the S-7100 have a black cover around most of the knobs with the exception of the Tuning and Loudness (power/volume) knobs. The S-7100 knobs are all silver with the exception of the Tuning and Loudness knobs. So, they basically reversed the knob design from the S-7100 to the S-7100A.
The S-7100A has a few more watts per channel at around 25 and the interior circuitry as well as the back panel differ from the S-7100. Both units have very nice walnut veneer wood cases which is unusual for non top of the line receivers.
While the Sherwood receivers were well built and performed as well as the other major brands they do not have the notoriety the others do. Because of this, prices are not as high as say a similar Pioneer or Marantz receiver. Of course, this also means that you can usually find a very good deal on these receivers.
