Sony PS-4750

The 1976 Flagship Model


This beautiful ‘Made in Japan’ turntable was top of the 1976 Sony range. It is in excellent physical condition, full & perfect working order and comes fitted with a good quality Sony / Audio Technica MM phono cartridge (with perfect stylus tip).


The following information and specifications are from the excellent vinylengine.com website:


“The Sony PS-4750 uses the new material SBMC (Sony Bulk Mould Compound) in the construction of its turntable platter and cabinet. Together with the use of servo-controlled direct drive DC motor, this new material with its unique acoustic and vibration absorption properties provides an excellent signal to noise ratio. An innovative frequency sensing device is utilized in the stereo control system in the form of a magnetic coating inside the platter. This unusual frequency generator (FG) component of the servo system, contributes substantially to the exceptionally low degree of wow and flutter. Newly engineered rubber insulation mats isolate externally caused mechanical vibrations that would have an adverse effect on the quality of reproduction. The high compliance, low friction tonearm is provided with a precisely engineered anti-skating compensator for proper tracking and superb reproduction throughout the audio spectrum. Other features of the PS-4750 include a high-visibility stroboscope, a built-in stylus overhang checker, a cueing lever to prevent record and stylus damage, and convenient pitch controls for accurate tone reproduction.
