Kenwood KA-2002A (1977–1980)

The Kenwood KA-2002A is a stereo integrated amplifier produced from 1977 to 1980. It sits in the lineup between the KA-2002 below it and the KA-4002A above it. It's a straightforward, mid-range Japanese integrated amp from the late seventies. Specific design details and market context are thin in the surviving record.

What is documented: 55 watts RMS per channel into 8 ohms, rising to 85 watts into 4 ohms. Input sensitivity is rated at 2.5 mV for phono and 150 mV for line. Signal-to-noise ratios are 75 dB (phono) and 90 dB (line). The damping factor is listed at 40. It measures 430 x 140 x 295 mm and weighs 8.1 kg.

There are a couple of spec conflicts between sources. THD is given as both 0.03% and 0.05%, and frequency response appears as both 20Hz–20kHz and 5Hz–100kHz. The wider frequency response figure is likely the general specification while the narrower one may be a power-bandwidth rating, but as the sources present them they conflict, so take either with some caution. High Fidelity (October 1973, p.62) covered the broader integrated amplifier market of the era, but specific press coverage of the KA-2002A itself hasn't surfaced in the usual archives.
