1. Features

Fully automatic mechanism

* Automatic playing for records of all sizes - 30, 25,
17cm (12",10", 7).

* Cueing facility protects the record surface during manual
playing.

* Repeat memory facility for automatic playing
repetition. Set the dial to hear up to six repetitions of a
record, 0r set it for infinite repetition.

* Automatic reject facility
To stop playing a record at any point, push the
START/REJECT operation lever towards "REJECT",
and the tonearm will automatically returns to the arm
rest.

New gimbal support arm

Outstanding tone arm sensitivity is assured, because

bearings for c|ockwise/counterclockwise rotation are

provided above and under the pivot bearing.

JL-F30
No. 2404

Trackability is thanks to the TH (Tracking Hold) system ~
the axis of the balance weight is positioned lower than the
pivot bearing, so superb tracking characteristics are main-
tained even if a record is warped or if there is external
vibration.

Belt-drive system

A drive belt connects the motor pulley to the platter.
Because motor vibration is not transfered directly to the
platter, the signal-to-noise ratio is much higher than that
of rim-driven turntables.

Large platter (0.5mil diamond tip)

30.9cm diameter aluminum die-cast platter.

Diamond stylus

Anti-skating mechanism

Anti-skating force can be adjusted corresponding to the
tracking force.
