Sharp SX-9800 High Power Stereo Amplifier This amplifier has been tested and works well on the main speaker outputs A and B. There is no signal from the rear speaker outputs, this maybe due to the fact that you need the companion system for this feature to work. The main power cord was cut and taped back together with black electrical tape, but works fine. Thank You
Is US$150 the right money for this one? Against recent comps, it lands above the US$92 median but still well below the US$182 75th percentile, so this reads as a fair-to-good asking price rather than a bargain or an overreach.
The upside here is the kind of vintage Japanese solid-state piece that appeals to collectors and listeners alike: substantial build, strong output reserves, and the sort of presentation people buy these for in the first place. At this level, the buy is really about condition and originality, so a clean, unmolested example with working controls and no repair history is the sweet spot. If it’s serviced, complete, and cosmetically honest, US$150 is a sensible entry point.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Sharp is a Japanese electronics company founded in 1912 by Tokuji Hayakawa, who began with a small metalworking workshop in Tokyo. The company’s name comes from its early “Ever-Ready Sharp” mechanical pencil, and its broader corporate identity grew out of a long history of practical consumer innovation rather than specialist audio alone.
In audio, Sharp has been associated mainly with mainstream consumer hi-fi and AV rather than ultra-audiophile hardware. Over the decades it has produced items such as radios, televisions, receivers, and other home-electronics components; in the modern era its audio presence is tied more to compact systems and mass-market electronics than to a deep catalog of standalone amplifiers, DACs, turntables, or headphones.
In market terms, Sharp is best understood as a heritage Japanese consumer brand with periodic involvement in audio, not a dedicated high-end hi-fi marque. For knowledgeable buyers, that means the brand carries historical legitimacy and recognition, but its reputation is closer to reliable mid-market electronics than boutique or reference-grade specialist audio.
