US$130 is fair to slightly good for a KC-206 if it’s complete and cosmetically decent; it’s not a steal, but it’s comfortably in the buyable zone for a working vintage Kenwood control amp. The model dates to 1987 and sits in the sweet spot of late-’80s Japanese hi-fi, with a rated 10 Hz–70 kHz response and very low stated distortion, so value is mostly about condition and function rather than rarity hype.
What makes it worthwhile is the useful, flexible control section: phono/MM support, line-level switching, and the built-in 7-band EQ-style feature set that can really suit a system needing a bit of tone shaping. If the unit powers up cleanly, all switches behave, and the faceplate is tidy, this is a solid enthusiast buy; just make sure the seller can confirm no scratchy controls, channel dropouts, or missing knobs, since age-related service issues matter more than with a modern preamp.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Kenwood traces its origins to December 21, 1946, when it was founded as Kasuga Radio Co. Ltd. in Komagane City, Nagano Prefecture, Japan, by a group of entrepreneurs led by William "Bill" Kasuga. Emerging in the postwar era, the company initially produced electronic components and amateur radio gear, renaming to Trio Corporation in 1960 before adopting the Kenwood name in 1986 to appeal to Western markets—blending "Ken," a familiar name across Japan and America, with "Wood" evoking durability and Hollywood. This rebranding fueled rapid international growth, starting with a U.S. office in Los Angeles County in 1963.
The brand built its legacy on high-quality audio and communications equipment, excelling in home hi-fi amplifiers like the acclaimed 1970 Supreme 1 multichannel model, receivers, tuners, and speakers with innovations such as polypropylene cones. Kenwood also pioneered car audio systems, including the first audio/video amplifier for home theater in 1981 and anti-theft cassette decks, alongside professional two-way radios and amateur transceivers. While maintaining roots in consumer electronics, it expanded into automotive infotainment.
Today, as part of JVCKENWOOD since the 2008 merger with JVC, Kenwood holds a solid mid-tier position in car audio and professional communications, prized by enthusiasts for reliable performance and aftermarket upgrades. Its vintage home hi-fi gear from the 1970s and 1980s commands respect among collectors for robust build and warm sound, though it no longer dominates pure hi-fi markets.
