* This new measuring method concerns only the turntable assembly, in¬
cluding the platter. It excludes wow and flutter caused by the tonearm, the
cartridge, or the record. Measured by obtaining signal from magnetic pick¬
up head.
The following trouble checks will help you correct most common
problems encountered with a turntable system. Should any pro¬
blem persist after you have made these checks, consult your
nearest Sony service facility.
Before proceeding with these trouble checks, first refer to the con¬
nections and the operating procedures on page 6.
Impaired tone quality
• Improper tracking force. See “Tonearm adjustment’’ on page 4.
• Dusty stylus.
• The turntable is not placed on a level surface.
• The turntable is incorrectly placed on or too near a speaker.
• Worn stylus or defective record. (The stylus life is approximately
400 hours of playing time.)
• Incorrect stylus installation.
• Improper tonearm balance.
• Improper setting of the anti-skating compensator.
No audio from one channel
• Loose attachment of the cartridge shell to the tonearm.
• Poor shell connection. Wipe the connector pins with denatured
alcohol.
• Loose connection of phono connecting cord.
• Low volume level setting for one channel of the amplifier.
Groove skipping, tonearm tends to skate, tonearm does not ad¬
vance.
• Improper tracking force. See “Tonearm adjustment” on page 4.
• Improper setting of the anti-skating compensator.
• The turntable is not placed on a level surface.
• Defective record.
• External vibrations.
Steady low-pitched hum
• Loose connection between the cartridge shell and the tonearm.
• Loose connection of phono cord.
Loud rumble or low-frequency howl *
• The turntable is affected by external vibration.
• The turntable is too near a speaker.
♦ T h i s is called “acoustic feedback” and is caused when vibrations from the
speakers are transmitted through the air or via solid objects (such as the
shelves, the cabinet, the floor, etc.) to the turntable, where it is picked up by
the stylus, amplified and reproduced through the speakers once again.
