The Technics SL-J2 is a quartz-controlled direct-drive fully automatic turntable system produced by Technics between 1984 and 1988. It features a linear tracking tonearm with an optical sensor that allows for the kind of track-skipping more typical of CD players. The sensor also detects the size of the record sitting on the platter (7-inch, 10-inch, or 12-inch), which allows the needle to drop precisely on the first track.

Product description

From the original Technics SL-J2 brochure:

"Who else but Technics could put so much high performance, and so many convenient features in such a slim body? The SL-J2 features the outstanding rotational speed accuracy of quartz-referenced direct drive, and a linear tracking tonearm for perfect tracing accuracy. The convenient skip/search/direct access function allows you to skip over selections you don't want to hear. A separate, easy-to-read Music Select LED confirms your skip/search commands."
