Bauähnlichkeit to the TC-K715S and TC-K717 IT, with which the 815 S also divides the Service Manual.
bigger brother of the TC-K715S (which has a single-capstan drive)
capstan shafts in continuous operation
control disc ("GEAR MODE CAM C") SONY P/N 335674701 prone to wear, because plastic
mechanics are easier to apply than on ES-class devices.

Test (short) in Audio 11/1994: Very good, top class, 85 points (!), 4 Ears (!)
Stereo 3/1995: Profile in comparison test with 5 other tape decks, p.19: Good, 1 star (*): "solid, quartz-controlled 3-motor drive with double capstan drive, plus Sony 's typical measuring circuit for bias and level, and on top of that 4 Dolby S chips for optimal dynamics - this deck has everything the heart of the recorder fan desires. By the way, it is neatly processed and does not disappoint sonically either. Only sometimes you think, for example with women's voices, that the playback sounds a bit too brittle."
