Fisher 90 (circa 1956–1958)
Not much is preserved about the Fisher Model 90 as a catalog number. The record comes entirely from period advertisements and reviews, which show the model in at least three variants - the 90-T FM-AM tuner, the 90-R FM-AM tuner, and the 90-A audio amplifier. Surviving sources don't say whether these were successive revisions, simultaneous products, or a coordinated series.
The 90-T was advertised as a full-feature FM-AM tuner on a single chassis. HiFi-Stereo (February 1958, p.21) pushed an “astonishing 0.85 microvolt FM sensitivity,” which it credited to the “celebrated FISHER GOLD CASCODE RF amplifier” and “widest-band circuitry.” The ad also promised “eleven momentous features” plus twenty others, including Microray Tuning, Fisher’s visual tuning aid, and adjustable-selectivity AM reception. The 90-R, covered in High-Fidelity (November 1957, p.24), was also an FM-AM tuner. It “combines engineering excellence and dazzling performance,” and was reportedly capable of delivering “maximum sensitivity and maximum signal-to-noise ratio, without compromise.” The same source claimed the 90-R “may even bring in FM stations before you have connected the FM antenna.”
The 90-A was a power amplifier. An advertisement listed the “Model 90-A” as a “90 Watt Audio Amplifier,” next to the smaller 55-A (55 watts) and 80-AZ (30 watts). That put it at the top of Fisher’s amplifier line at the time. No other electrical specifications, such as distortion figures, frequency response, or damping factor, have been located.
The Fisher 90 series existed in the late 1950s as a set of high-performance tuner and amplifier components. Precise production dates, retail prices, and total quantities are unrecorded in the materials available to the Archive.
