Speed
The Garrard Type A Auto Turntable is designed to give the desired
turntable speed within close tolerances. Should, however, the turn-
table
run
excessively
fast
or
slow,
the
motor
pulley
may
not
be
correct
for the frequency of the power supply. These pulleys are colour finished
for identification, Nickel for 50 and Brass for 60 cycles. To gain access
to
the
motor
pulley,
remove
the
turntable
as
described
on
page
five
under
“Maintenance”.
Should the speed vary during playing, examine the motor pulleys,
rubber
intermediate
wheel
and
inside
of
turntable
rim
for
traces
of
oil,
wipe
thoroughly
with
a
clean
cloth.
Check
that
the
motor
pulley
is
in
its
correct
position
on
the
motor
shaft
and
that
both
screws
are
tight.
See
that
the
intermediate
wheel
runs
in
the
centre
of
the
appropriate
pulley
step
and
does
not
rub
on
the
side
of
the
adjacent
step.
If
necessary,
loosen
the
screws
holding
the
pulley
to
the
shaft
and
move
pulley
to
its
correct position.
Motors
If
the
motor
fails
to
start
when
the
unit
is

check
the
power
supply
to
see
that
current
is
reaching
the
motor.
Also
check
the
switch
and
see
that
the
switch
blades
are
clean
and
making
good
con-
tact,
position

Check
the
position
of
the
voltage
change
over
links
on
the

make
sure
the
motor
is
suitable
for
the
voltage
—
of
the
power
supply.
