Kenwood KT-700
The Kenwood KT-700 is an FM stereo tuner.
The headline figure is the sensitivity: 0.9 µV. That's a very strong number for the era, putting it in the company of tuners that cost considerably more. HiFI-Stereo (October 1968, p.17) covered the closely related KT-7000 model and noted its use of three FETs and a four-gang tuning capacitor to achieve its 1.5 µV sensitivity, along with crystal filters and ICs for selectivity — and the KT-700 appears to sit in that same engineering generation. The KT-700 itself is rated at 75 dB signal-to-noise ratio, 0.15% distortion, and 80 dB selectivity. Frequency response is spec'd at 30 Hz to 15 kHz ±0.5 dB, with a healthy 1.4V output. Those are numbers that hold up well even by early-'70s standards.
Beyond the specifications, the record is thin. No design details, no original price, no dimensions or weight have surfaced in the documentation available to the Archive. Kenwood was fielding a serious FM tuner here, aimed at listeners who cared about pulling in weak stations cleanly. It would have sat atop a rack feeding a separate amplifier.
