Nakamichi 430 (1977–1979)

Name: Nakamichi 430
Brand: Nakamichi

The Nakamichi 430 came out of the company's late-1970s push beyond cassette decks into separates. It was a compact stereo receiver that paired with the 410 preamplifier and 420 power amplifier in period advertising. Nakamichi's own campaign in High Fidelity (December 1977, p.93) called the trio "the most elegantly compact, best performing trio of components on the market today." Each unit measured under 9″ × 16″ × 3¼″ and was arranged vertically to take up less space than most receivers. The 430 itself was the tuner-amplifier of the set. It was rated at 30 watts per channel into 8 ohms from 20 Hz to 20 kHz at 0.08% THD, with a Class AB design and two separate power supplies.

Documentation on the 430 is thinner than on Nakamichi's cassette decks, and what survives is mostly spec-sheet material. The tuner section had an IHF usable sensitivity of 1.9 µV and 40 dB stereo separation at 1 kHz. The phono stage accepted 2.5 mV and the line input 150 mV. Signal-to-noise was rated at 90 dB (IHF). The tone controls had turnover point switching, and the unit had output limiter circuitry. The MSRP was $550, and production ran from 1977 to 1979.

A few specifications conflict across sources. Frequency response is listed as either ±0.2 dB or ±0.5 dB, and damping factor as either 60 or 100. No authoritative document settles it, so treat those figures cautiously. The 430 measured 434 × 128 × 333 mm and weighed 9.9 kg.
