YOUR
NEW
CARTRIDGE

The Pickering TLZ/

7500 MKiis Cartridge was

designed to be used in stereo

systems which have high gain,

low impedance MC inputs or use ex-

ternal head amps with input impedance

of 100 ohms or higher. It is a moving mag-

net pickup system with Iow impedance coils

allowing the use of long cables between the turn-

table and the preamp. The frequency response ex-

tends to beyond 50 Khz. The low frequency tracking is

superb along with excellent high frequency tracing ability.

THE STEREOHEDRON 11" STYLUS is shaped to provide an

enlarged record groove contact area, while providing the ability to

accurately trace the high frequency, high level modulations of todays

records. The Stereohedron 11" stylus provides superior performance with low
stylus and record wear for your records.

_SOME IMPORTANT FEATURES OF THIS CARTRIDGE

DUSTAMATIC" BRUSH - A patented feature of Pickering Cartridges is the
inclusion of a brush assembly that helps keep the record grooves clean. it does
not in any way detract from the overall performance since the brush assembly
is independently suspended from the cartridge. The brush is located off-center
to allow it to clean the record grooves ahead of the stylus. (Useable for 1/2
mounting applications only).

V-GiUARDm PROTECTION - The stylus assembly on your cartridge has mold-
ed into it a precisely shaped opening which we call a V-Guard" , into which
the stylus recedes in the event of excessive downward or sideways pressure.
But nothing can make up for carelessness. always treat your records and
cartridge with the respect any precision instrument deserves.
REPLACEABLE STYLUS - The patented stylus assembly is removable. Simp-
ly grasp between the tips of the thumb and forefinger. Pull gently to remove
the stylus assembly. Although the stylus assembly is sturdily constructed, please
handle it carefully when removing and replacing it.

RECORD CARE - To insure proper cleaning of your records, the use of Picker-
ing Record Cleaner Kit with RC4 PLUS is recommended.

STYLUS TIP CARE - Dust will inevitably accumulate on the stylus tip even
under the cleanest conditions. it can be removed by a gentle brushing forward
with a camels hair, or similar brush, such as supplied in the Pickering Stylus
Cleaner Kit, 804'".

Damaged or worn styli can do irreparable harm to your record collection. Check
your stylus after every 250 hours of record playing time, and replace it when
worn to protect your records. Always insist upon a genuine Pickering replace-
ment (imprinted with the Pickering Logo)-an imitation will significantly reduce
performance and increase record wear.
