Fisher RS-1052
The Fisher RS-1052 is a solid-state receiver from the mid-to-late 1970s. Period listings describe it as one of the larger Fisher receivers of the 1975-1978 era. Past that, the record is thin. No production years, original price or detailed design information survive in the sources available. What is known is a set of published specifications.
The amplifier section was rated at 85 watts per channel into 8 ohms, from 20 Hz to 20 kHz, both channels driven, with no more than 0.1% total harmonic distortion. That is a substantial figure for a consumer receiver of that period. The phono stage had an RIAA-accurate response of 20 Hz - 20 kHz (±1 dB), 2.5 mV sensitivity and a 65 dB signal-to-noise ratio (MM). Line inputs were rated at 150 mV sensitivity with an 85 dB S/N, and line frequency response ran from 10 Hz to 50 kHz (±1 dB). Damping factor was specified at 60.
The FM tuner section was reasonably specified too: 2.5 µV (IHF) sensitivity, 70 dB mono signal-to-noise, 40 dB stereo separation at 1 kHz, 60 dB selectivity and a 1.5 dB capture ratio. AM sensitivity was rated at 300 µV/m. The chassis measures 19" wide by 6" high by 14.5" deep and weighs 38 lbs.
Audio (October 1978, p.86) covered Fisher receivers of this generation in its test reports and placed the RS-1052 among the brand's larger offerings of the era.
