OPTONICA RP-7705 TurntableThis rare unit works and plays great at both 33 & 45 speeds. The fine tuning knobs for both speeds are stiff and when turned do not affect speed at all. Speed remains locked. Tonearm cues up and down, drops right where it should and rejects properly. The APLD buttons click & light up and cause the arm to lift and search, but sometimes it finds the track correctly, sometimes it does not. Perhaps cleaning the infrared sensor would fix this. Tested and working - please read description above.The glass dust cover is in great shape & the hinges function properly.Audio Technica headshell installed with what appears to be an Audio Technica AT4030 cartridge.

At US$400, this lands just above the US$394 median and well inside the normal used range, so it reads as a fair ask rather than a standout bargain or an overpriced reach.
That makes it interesting if the deck is complete and clean, because this is a respected quartz-direct table with lock stability and the sort of dependable, fuss-free performance many buyers want in a vintage spinner. For a pickup-only listing, the upside is local inspection and no shipping risk; just confirm the arm, platter, auto functions, and dust cover are all behaving properly, since those details matter more than chasing a bargain here.

# Optonica
Optonica was a high-end audio subdivision of Sharp Corporation, the Japanese electronics manufacturer. Launched in 1975 (with some sources citing 1976), the brand was created to compete directly with established premium audio makers including Pioneer, Yamaha, Sansui, Nakamichi, and Marantz during the golden age of hi-fi. Sharp designed, built, and marketed Optonica products entirely in Japan, positioning the line as a serious contender in the luxury stereo market.
The brand's product portfolio centered on integrated amplifiers, receivers, and complete stereo systems aimed at discerning audiophiles. Optonica equipment was engineered to deliver high-fidelity sound reproduction across the mid-to-high power range, with models typically rated between 40 and 60 watts per channel. The brand maintained a focused approach, concentrating on core audio components rather than diversifying across numerous product categories.
Optonica's tenure in the high-end audio market proved relatively brief, effectively ending by 1982 as a serious competitor. The brand was revived in 1988 as a consumer electronics line encompassing stereo television receivers, VCRs, portable cassette players, and surround-sound receivers, but this iteration lacked the prestige of the original audio division. Production ceased entirely by 1991. Today, Optonica equipment from the late 1970s and early 1980s holds appeal among vintage audio collectors and enthusiasts seeking well-engineered Japanese hi-fi from that era.
