It may not look like much to you. But this is one of the first-ever products of the Fisher Radio Corporation, and is so rare that no hifi collector that I know has ever seen one–or even an ad or catalog listing for it. This particular one was found recently by John Eckland at a Palo Alto garage sale. Made circa 1953. It is a copy of the more-common HH Scott dynamic noise suppressor, made with miniature instead of octal tubes. The “Eye” tubes on each side of the panel display the operation of the bass and treble noise gates, respectively.
There was a special amplifier for it, but John didn’t find the amp chassis. So he will pair it with the Fisher 60 triode amplifier seen in the 3rd photo, for some historical parity. Imagine a home hi-fi system using this stuff, plus a large rackmount preamp, perhaps a rack-mount REL Precedent FM tuner, and a Rek-O-Cut turntable with a GE variable-reluctance magnetic cartridge mounted on a massive Gray tonearm. All feeding a huge Altec Voice of the Theater horn speaker. Top-end for 1953.
