Sherwood High Fidelity Stereo Equipment
Diese Firma hat es meines Wissen nach 2 mal versucht, "über den großen Teich" zu uns nach Europa zu kommen. Die Produkte waren von der Qualität breit gestreut. Es gab also durchaus Spitzenproduke und dazu viel Mittelmaß, das auf dem Image der oberen Spitzen-Linie mitschwamm.
An diesem Produktprogramm konnte man gut erkennen, wie der Umschwung von Mono zu Stereo vollzogen wurde. Es gab Stereodecoder zum Nachrüsten, wie bei den anderen auch, und es gab Stereovorverstärker mit nur einer Endstufe auch zum Nachrüsten.

(6) MODEL S-3000 III FM/MX TUNER
FM tuner featuring in addition to its sensitive circuitry, internal plug-in space for FM multiplex reception of stereophonic multiplexed broadcasts. Reduction of distortion caused by FM station over-modulation and better long-distance reception is achieved through incorporation of "corrective" inverse feedback. Noisy "hash" is eliminated between channels through the use of FM Interchannel Hush. AFC corrects by 90% any mistuning of a station and no drift is experienced. Disabling (AFC) switch on front panel and local-distant switch allows easy reception of distant signals. Circuitry includes low noise balanced antenna input transformer, triode mixer, IF amplifier and three cascaded limiters, Foster-Seeley balanced discriminator, delayed AGC applied to RF stage, interchannel noise muting with front panel level control, 3 db inverse feedback from discriminator to AFC tube.
Features: Interchannel Hush control; Stereo-balance control; Level control; "Aero-Beam" tuning eye; Corrective feedback increasing discriminator bandwidth to over 1 mc and IF bandwidth to 290 kc without sacrificing tuner selectivity.
