Nikko A-400 (c. 1980)

Not much is documented about the Nikko A-400. Nearly everything on record comes from one period test-report page. HI-Fi-Stereo-Buyers (January 1980, p.58) covered it under amplifier test reports and described an LED output-power display. The smallest step between LEDs was 3 dB. The meter was noted as optimistic - it could show 300 watts when the actual output was 150 watts. The same report inferred a frequency response within roughly ±3 dB from 20 Hz to 20 kHz, based on the display varying by one LED step across the band.

Beyond that page, the trail goes cold. No rated power, original price, dimensions, or production years have turned up in the source material at hand. The A-400 seems to have drawn little attention in the later stereo press.
