Kenwood KA 60
Little is documented about the Kenwood KA 60. It appears to have been a compact integrated amplifier in Kenwood's early-1980s "Slimline" separates series. The company's own advertising placed it a step below the 48W KA-80 in the same lineup. Beyond that, the surviving record amounts to a couple of short period notices.
Audio (December 1979, p.32) described the KA-60 as a "high-speed d.c." integrated amplifier. The DC-coupled circuitry was said to respond to transients instantly, avoiding the timing lag that produces spurious distortion or transient intermodulation. It used dual power supplies to eliminate crosstalk. It was rated at 60W RMS per channel - both channels driven into 8Ω from 20Hz to 20kHz - with THD below 0.02%. Price at the time: $399.00.
A year later, Kenwood's own Slimline advertising listed the KA-60 at 30W per channel into 8Ω, 20Hz to 20kHz, with 0.03% THD. Exactly how the two ratings relate isn't clear from the material that survives. No full review, manual, or measurement report has surfaced in the archive. What the period record shows:
- Integrated amplifier, Kenwood "Slimline" series (Kenwood advertising, September 1980)
- 60W RMS/channel into 8Ω, 20Hz–20kHz, THD < 0.02%; $399.00 (Audio, December 1979, p.32)
- 30W RMS/channel into 8Ω, 20Hz–20kHz, THD < 0.03% (Kenwood advertising, September 1980)
- DC amplifier design with dual power supplies (Audio, December 1979, p.32)
