Sony's little big star for three short years, with a derived professional LP drive available in two versions: TTS-8000 (july '76) and TTS-6000 (october '77).

The Magnedisc & X-tal Lock systems weren't really Sony inventions (ie. Denon) but the marketing tags were: the X-tal compares the reading of a magnetic strip printed inside the platter's rim with a Quartz oscillator to further insure speed stability. The system was featured on many Sony units from World receivers to the TTS-8000 or PS-X9 masterpiece.

The fitted tonearm is a variation of Sony's own PUA-1600S (S for short) version, a tonearm one could purchase separately to fit even higher grade turntables ; the version used on the 8750 had a carbon-fiber tube. The headshell is also carbon-clad (SH-160). The PS-8750 was also adorned with a special OL-2K mat containing a micron-thick plastic "skin" itself containing a very thick oil. Other nice touches: the lid has an anti-static treatment, the output plugs are gold-plated and the arm's pivot rests on two sapphire bearings.

Owning a TTS-8000, I can say that if the oil still is everywhere within its pocket, almost 30 years of use have disformed the outer part of the mat itself where the oil concentrated too often... That mat, however, still sounds better than the average mat or any Thorens mat for that matter.

An AES article describing the improvements over turntable design through the PS-8750 can be found (bought) right here. More about the PS-8750 in this AK thread : how to lock the tonearm before shipping and nudies of the base.
