Not restored. ive had it hooked up in my house and it all works. I also have the matching stereo, but it needs some repair.
Sharp’s SM-7700 sits in that solid late-era Japanese stereo power amp lane: capable, understated, and appealing to anyone who wants honest vintage muscle without the trophy-tax. At US$200, this is a touch above the median used ask of US$177 and over the 75th percentile at US$188, so it reads as ambitious rather than a bargain.
That said, it’s not outlandish if the amp is clean, unmodified, and fully functional; well-kept examples of these amps earn their keep with smooth drive, good dynamics, and the sort of build quality many vintage fans still value. If it includes the original box, manual, or proof of recent service, the premium is easier to justify. If not, a buyer should make sure the protection relay, controls, and channel balance are all behaving properly before paying top dollar.
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.
