Sony PS-X65 DD Turntable Quartz X TAL-LOCK System Full Electronic Microprocessor Controlled Magnetic Tracking


My New entry, not working, turntable Sony PS-X65 substitue of other Sony Direct Drive Turntable
 Sony PS-X60. Only better S/N ratio for the specs, but it has more charm.

Speed is correct and Locked, both 33 1/3 and 45 rpm, in manual play it's perfect only a little trouble on the mute switch, easily solved.
In automatic play tonearm doesn't stop and doesn't retun to stop position...

Quartz X TAL-LOCK SYSTEM

It Spinning well!


It look so beautifull..

Automatic actions are guarantee by 2  electronic controlled motors, no mechanicals devices like his predecessor, PS-X60.
The Horizontal motor is used also for the correct Traking Force


There are 2 coaxial "brushless" motors: one for the lift the other,
you can see the coils, for the Horizontal Movement
