Onkyo A-100
Little is documented about the Onkyo A-100. The record shows an integrated amplifier made by Onkyo Corporation, a maker known for solid, no-nonsense electronics and a reputation for reliability and clean performance. It turns up in reference lists of classic Onkyo models. Beyond that, the trail goes quiet.
No verified technical specifications survive. There is no power output, no input count, no dimensions, no production date, no original pricing, and no design or circuit details. No period review of the A-100 has surfaced in the material on file. The closest Onkyo item from that era on hand is High Fidelity (September 1988, p.16), which covered the TX-SV7M, an AM/FM receiver with a 100-watt stereo amp - a very different model. Nobody can say with confidence where the A-100 sat in Onkyo's lineup. It may have been a modest mid-tier unit, quietly built and quickly overshadowed, but that's conjecture, not documentation.
The model does exist in the wild. One eBay listing paired an A-100 with an Onkyo T-100 tuner as a "vintage stereo set" at $280. A separate used listing from January 2, 2026 was offered at €85. Completed sales over the past twelve months range from roughly $71 to $171, with a median of $171. That is based on just two sales, so it is not much of a trend.
