Harman Kardon A-100
Documentation on the Harman Kardon A-100 is thin. The surviving record consists of a single spec source — no original pricing, no production history have turned up in the archive. What is known: this was a solid-state integrated amplifier rated at 35 watts RMS per channel into either 4 or 8 ohms at 1 kHz, with total harmonic distortion under 0.5% and intermodulation distortion under 1%. Period equipment profiles in Audio magazine covered the matching F1000T tuner, designed to match the A1000T in appearance, human engineering, and performance Audio (June 1964, p.51).
The A-100's frequency response was wide for its era — 10 Hz to 100 kHz at +0/−3 dB — with a signal-to-noise ratio above 70 dB (unweighted). Tone controls offered ±12 dB at 50 Hz (bass) and ±12 dB at 10 kHz (treble). It measured 440 × 110 × 280 mm and weighed 7.2 kg.
One caution: no production years were confirmed in the research. If you own an A-100 or have a manual, brochure, or period review, that would help fill in the gaps considerably.
