Type scm Stereo Cartridge

This cartridge will satisfy the most discerning audiophile.

Examination of the specification and response and
separation graphs will confirm our claim but it is the
listening test which is the most revealing. The channel
separation is well maintained to both ends of the
frequency spectrum resulting in a well defined stereo
image in correct perspeczive. The high compliance and
low mass of the stylus system in conjunction with a
well designed arm allow extremely low downward
pressure to be accomplished giving improved perform-
ance and reduced record wear.

We unreservedly claim this is one of the best stereo
cartridges available to-day.

INSTALLATION

To realise the full performance specification of which this 3'3: afihgggh'
cartridge is capable. the following factors must be borne H , .
in mind when installing. Thhe valulgflot till: .
(I) The tone arm employed must have a sufficiently free :th 3:5; HP! v
and unrestricted movement in both its lateral and vertical

directions of travel otherwise it would be adversely These are

aflected. For example. if the cartridge is required to play intended" for us
with a downward force acting upon it of two grammes ., ~ »

_ . . .. conditionrofl
and it IS fitted In an arm requiring one gramme to over- . .

come friction in either at lateral or vertical direction. a
force of three grammes will be required to lteep it
playing correctly. Therefore. a good arm is required for
the full capability to be realised.

(I) In no circumstances should the maximum playing
weight be exceeded or the performance of the cartridge
will be adversely affected. To ensure correct stylus angle
the under surface of the pickup tone arm should lie parallel
to the surface of the record when viewed from the side
with the pickup on the disc. The cartridge should also be
mounted in the head shell or cover so that when viewed
from the front the stylus is perpendicular to the record
surface. The tone arm itself should be positioned in
accordance with instructions given by the manufacturer.
thus assuring minimum tracking error and distortion.

REPLACEMENT OF THE STYLUS SYSTEM

To remove the stylus view the cartridge from the underside. The small plastic fitting holding the
stylus assembly WI" slide backwards and out of the cartridge body leaving the flexible coupling
on which the stylus rested. The new stylus can be fitted by sliding it baclt into position. taking
care that it rests firmly in the small slot in the flexible coupling. lt may be necessary to pull the

henble coupling baclt with a pm. so that the coupling lies centrally in the gap of the cartridge
base through which ll protrudes.

When correctly fitted the diamond stylus should protrude slightly below the moulded guards of
the cartridge bate.
