Vintage high end cassette tape deck. See this review: http://www.hifi-classic.net/review/technics-rs-m270x-331.html
Extract "The Technics RS-M270X is a two-head, two-motor cassette deck incorporating both the Dolby B and the dbx II noise-reduction systems. Its solenoid-operated tape transport is controlled by light-touch pushbuttons, with an IC logic system that makes it possible to press the buttons in any sequence without risking damage to the machine or to the tape. The transport controls can also be operated through a wired remote-control accessory that plugs into the rear of the recorder.
The tape-drive capstan is part of a direct-drive servo-controlled d.c. motor, with a second d.c. motor turning the tape hubs. The combination record/playback head (called the SX head by Technics) is made of permalloy and Sendust. Together with the Sendust-alloy erase head and high-power bias/erase oscillator, it makes the recorder fully compatible with metal-alloy tapes."
Work well (all controls function, everything rotates the way it should). Selling it "as is". Often the rubber bands/belts can age though for about $12 you can get a replacement set.
