Luxman K-220 (1978–1981)

The Luxman K-220 is a stereo cassette deck from the late 1970s. It is a two-head, single-motor design, and Luxman sold it in Japan from 1978 through 1981 at ¥69,800. It was a more accessible deck sitting alongside the company's higher-end models. Later champagne gold advertising grouped the K-220 with the L-400 amplifier and T-240 tuner as a coordinated system. Luxman's own copy called it "precise hand-crafted electronics" and "pure, clear sound."

Documentation on this model is modest. The Japanese spec sheet gives the essentials: 4-track, 2-channel stereo at 4.8 cm/s, wow and flutter of 0.07% (WRMS), frequency response of 30 Hz - 16 kHz on normal tape, and a signal-to-noise ratio of 58 dB with Dolby NR engaged. Input sensitivity is 0.3 mV for microphone and 70 mV for line, with line output at 580 mV. The unit measures 440 × 130 × 280 mm and weighs 6.5 kg. The power supply is specified as AC 100V, which is the Japanese domestic version. Export specifications are not documented.

Notably, the noise reduction is described only as "Dolby NR" in the record — the specific type (B or C) is not confirmed in available sources. High Fidelity (September 1984, p.20) mentioned the K-220 in a Luxman advertisement for its champagne gold series, pairing it with the L-400, T-240, L-210, K-240, and L-430 — a rare period sighting that places the deck within Luxman's coordinated component lines of the early 1980s. Beyond that, no substantive reviews or user commentary have surfaced.
