Reviews[edit]

  • Anno 1978, the PS-X 7 was the largest fully automatic turntable at Sony, next to the large Sony PS-X 9, which was also offered as a studio turntable.
  • The chassis was made of the low-resonance SMBC material in (plain) grey. This is an extremely hard mixture of PVC, aluminum, and yet another material that Sony is silent about. It is harder than some metals, I - "Phonogen" - found out when installing a new (thicker) cable.

Quartz-controlled direct drive (brooms up to 150 g are compensated without problems)

  • Synchronization fluctuations: 0,045%
  • Rumble noise voltage ratio: 79 dB
  • Extremely low-mass carbon tone arm with standard (SME) headshell
  • 3 plate sizes adjustable
  • Gel pad to increase the inertia of the platter
  • Sensor buttons (Start/Stop and Repeat) for vibration-free operation with closed hood
  • Optoelectronic limit switch
  • Stroboscope with own frequency (120 Hz !) for even more precise speed control
  • Similar Sony turntables:
  • "Phonogen": I had few problems even with the digital recording of the legendary Tchaikovsky 1812. Even top-class turntables had to give in, some vinyl and audio freaks claimed that the right-angled deflections of the record were not playable, but the Sony disproved this ;-)).
