Pioneer PL-7 Direct Drive Turntable

From top to toe, the PL-7 is replete with features only Pioneer can provide — like the PG low-mass straight tone arm, the Stable Hanging Rotor DC motor, a Quartz-PLL servo system, and much more.
 
Starting from the bottom, the PL-7’s base is a design we call Coaxial Suspension. It's an effective safeguard against mistracking and (in the worst cases) audible howling caused by acoustic feedback.
 
The arm and motor are isolated via spring-loaded rubber insulators from the cabinet. This Pioneer design shuts out floor- and air-borne vibrations completely. The significance of Coaxial
Suspension is best shown by the remarkable signal-to-noise ratio of the PL-7 — no less than 78dB!
 
Moving inside the PL-7, you'll discover the elaborate platter rotation system that provides constant speed accuracy. Central to this system is Pioneer's coreless DC motor. It forgoes slots, resulting in smooth, cog-free rotation. Brushes are replaced by semiconductor Hall elements for noiseless,
non-wear polarity switching.
 
The Stable Hanging Rotor crowning the motor ends platter wobble. And finally, the Quartz-PLL
servo system has eliminated the last vestiges of rotational speed aberrations so that wow
and flutter of only 0.025% (WRMS) is measurable.
 
Taking a look at the tone arm system, you'll find it is constructed on the low mass principle from tip to base. The arm is straight and made of Pioneer's PG (Polymer Graphite). Tough, lightweight and resistant to resonance, our PG arm displays all the desirableproper ties of the perfect tone arm.
 
Reproduction is faultlessly clean with even warp-induced distortion kept to extremely low
levels. The headshell, made of a low-mass resin, is offset to reduce horizontal tracking
error to a bare minimum throughout record play.
 
All controls except arm elevation are onthe slanted front edge and are light-touch sensitive. An indicator lights when the speed is quartz locked. Operation is all automatic  from lead-in to arm return and shutoff.
 
This turntable is fully serviced and fully operational.  Comes with a new stylus
