FEATURES
New Type Frequency Generator Servo Control
One of the major secrets behind the razor-sharp accuracy
and superb quality of sound lies in the new type (Fre-
quency Generator) servo controlled DC motor, and
greatly improved highly rellable IC circuitry. Even the
slightest hint of speed change and drift is corrected im-
mediately. 7
Electronic Speed Switching
Even though this turntable is belt-driven, gone is the old
conventional pulley type speed changing mechanism.
Speed switching in this unit is fully electronic, thereby
adding to the high degree of mechanical precision and
reliability.
All Front-Panel Controls
The advancement to complete front-panel contro! marks
a big step forward in turntable operation, not only be-
cause Of the greater convenience, but also because of the
greater protection from dust, as the dust cover can stay
closed,
Tonearm Cueing Controlled from Front Panel
The tonearm is raised and lowered softly by a viscous-
damped cueing lifter. Even with the dust cover closed, a
cueing can be easily performed as the control is located
on the front panel.

Fully-Automatic Operation |
All operations in the SL-230 are completely automatic,
yet mechanical movements are accurate and silent. Full
protection to records and stylus tip is assured. With the
memo-repeat feature, favorite records may be repeated
up to six times, or indefinitely.
Highly Sensitive Gimbal Suspension System
With the high-precision pivot bearings employed for the
horizontal and vertical journals of the tonearm, in
concert with the adoption of the gimbal suspension
system, a high-sensitivity arm of less than 7 mg friction
has been attained, thus making it possible to fully realize
the performance of high-compliance cartridges.
Independent Pitch Controls
Permits record speed (at both 33-1/3 and 45 rpm) to be
varied by up to 6%.
Precision Strobe [Huminator/Pilot Lamp
With the built-in strobe illuminator/pilot lamp, accurate
speed adjustments can be made rapidly and easily.
