Sherwood S-8800a

 First of a new breed  - from Sherwood.

This is what high performance is all about. A bold and beautiful new FM Stereo receiver bred to leave the others behind. 160 crisp, cleanwatts-power in reserve. Up-front, ultra-now circuitry featuring Field-Effect Transistors and microcircuitry. Front-panel, push-button command of main, remot, or mono extension speakers and loudness contour. Sherwood high-fidelity - where the action is - long on reliability with a three-year warranty.

 Sherwood presents its latest version of the world-famed S-8800 series All-Silicon solid-state receivers. Six push buttons control the choice of main or remote stereo speakers (or both simultaneously), loudness contour, stereo/mono selection, tape monitoring, and high filter.

Unique with this receiver are two front-panel jacks, one to operate stereo headphones and another to playback or record into a tape recorder (or cassette recorder). The tape jack can also be used in conjunction with the S-8800a rear-panel jacks for dubbing from one recorder to another or for simultaneous recording on 2 recorders.

 New features such as these are backed up by the latest engineering advances such as Microcircuitry in IF and Synchro-phase FM limiter/detector circuits (providing -60 dB AnM rejection and 2.0 dB capture ratio). Also featured are Field Effect transistors in RF and Mixer stages (enabling -95 dB cross-modulation rejection).

A power reserve of 160 watts (4 Ω music power) is available to operate 2 sets of stereo speaker outputs and also a mono speaker output on the rear panel. Superlative sound reproduction is provided by the Sherwood S-8800a FM rated at less than 0,15% distortion and stereo amplifier rated at 0,1% at normal listening levels.

All of Sherwood's solid-state receivers, which have long been acclaimed throughout the world for their reliability, now offer a full 3-year warranty on all parts.
