Model M75E-Dl9 is a high quality elliptical stylus Stereo phono
cartridge mounted in a retractile safety suspension system to
provide a scratch-proof, bounce-proof, feature to the operation

of an automatic turntable. The Model

fically for The Dual 1019,

The elliptical stylus cartridge is spring mounted in the pickup
head A maximum needle force of
face 'of the record. Forces in excess of approximately 2 grams
will cause either the plastic safety bumper at the rear of the
cartridge or the plastic bumper in the stylus grip to come
in contact with the record surface and thereby protect the record
from needle scratches and protect the needle itself from damage.

Perhaps the most .desirable advantage of all
Dl9 makes it possible to operate the turntable in situations
where a changer normally will not work well. These include such
adverse conditions as aboard a shi during a storm; in rooms
where modern dancing is done;
which shaky floors or unstable phonograph supports will normally

cause mistracking of the cartridge.

LABORATORY TEST FIN
test findings of the Shure
scrutiny Shure pays to all imitation Shure
laboratory tests show that the imitation stylus assemblies labeled
as replacements for the Shure Model N3D Stylus Assembly vary
drastically in important performance characteristics. For example,
the compliance varied from a

9.0 grams to track a record with a low compliance stylus and
grams with a high compliance stylus. The high compliancd stylus
retracted at
drag on
sponse at high frequency (relative to the lkc level) ranged from a

5.5db peak to a drop of 7.5db. Separation varied from "good"

(27db) to 'poor" (16.5db) aJ lkc. These flgures reve$ that there
is very little consistency in performance characteristic of the
imitation

In each of the categories shown above, the results ranged from
good to poor. As a matter of fact, only 10% of the samples met the
Shure performance standards for the Shure N3D Stereo Dvnetic
Stv1us.-In addition to our test flndines. our Service De~ariment

records show that an increas~ng nummbe'r of D netic ~hbno Car­tr~dges are be~ng returned because of poor perrormance-and our

examination has disclosed that most of these returned cartridges

are
