Features
The
Lenco
L
78
Record
player
is
a
precision
instru-
ment
of
true
Hi-Fi
quality
which
will
satisfy
even
the
most
demanding
music
lover.
The
instrument
can
be
used
for
stereo
as
well
as
monophonic
listening.
The
usual
speeds
of
16%/s,
33'/s,
45
and
78
RPM
can
be
pre-set
in
click-stops
and
the
speed
can
also
be
varied
continuously
from
30—86
RPM.
The
light
tonearm
of
the
L
78
is
a
first-class
example
of
fine
mechanical
precision,
and
guarantees
clear,
undistorted
sound
reproduction,
with
the
greatest
possible
protection
for
your
records.
The
tonearm
is
lowered
onto
the
record
by
a
hydraulically
dam-
ped
lowering
device
—
thereby
eliminating
the
pos-
sibility
of
record
or
needles
being
damaged
whilst
putting
the tonearm
onto
the record.
The
unit
is
SEV,
DEMKO, NEMKO,
SEMKO
and
CSA
tested
and approved.
Technical Description
The
very
silent
4-pole
motor
(44)
is
spring
mounted
onto
a
rigid
steel
baseplate.
The
dynamically
ba-
lanced
turntable
is
made
of
die-cast
zinc,
and
weighs
4 kg.
The
power
is
transmitted
from
the
conical
motor
shaft
(43)
to
the
turntable
by
a
rubber
covered
idler
wheel
(41).
The
speed
is
changed
by
moving
the
idler
wheel
on the motor
shaft.
The
miniature
ball-bearings
fitted
into
the
tonearm
allow
for
a
free
sideways
movement,
and
the
knife-
edge
bearing
keeps
friction
to
a minimum.
An
adjustable
sliding
weight
(5)
enables
one
to
set
the
stylus
pressure
exactly
to
suit
the
cartridge
being
used.
An
automatic
brake
(23)
comes
into
operation
when
the
turntable
is
switched
off.
All
tonearms
can
be
supplied
with
the
anti-skating
device
(3, 28, 29).
Every
L78
Is
supplied
with
a
centre
piece
for
re-
cords
with
a
large
centre
hole,
a
stroboscope
disc
for
exact
setting
of
speed,
a
stylus-adjusting
gauge
for accurate setting of stylus overhang, a set of
shock-absorbing mounting supports anda cut out
template
(only
required
for
chassis
model).
Unpacking the L 78
When
unpacking
check
for
possible
damage.
The
L78
is toroughly
checked
and
tested
before
leav-
ing
the
factory.
Any
damage
which
may
have
been
caused
during
transport
should
be
reported
imme-
diately.
In
this
connection
we
would
like
to
point
out
that
the upper
part of the knife-edge
balance
has been
put
into
the
lower
part,
i.
e.
it
is
held
there
only
by
the
weight
of
the
arm.
The
resulting
movement
which
can
be
felt
just
above
pedestal
spindle
when
lifting
the arm,
is a normal
and necessary
feature
of
this
type
of
bearing
and
should
not
be
mistaken
for a fault
or damage.
Preparation for Use
The L.78 is available on a wooden base, or as a
build-in
model.
To
avoid
damage
of
the
turntable
spindle during transportation, the turntable is
packed separately in a cardboard sleeve.
Models mounted on a wooden base are delivered
fully assembled and can therefore be operated
without
any
difficulty.
The
build-in
model
must
be
assembled
on
the
spot,
and
the
instructions
on
the
cut out template should be carefully followed. On
all models the spring-mounted motor (44) has been
secured for transit. This has been done by means
of two red securing screws (18) on the baseplate
under
the
turntable
and
these
should
be
losened
until
the
motor
is
freely
sprung.
The
L78
is
de-
signed
for
use
with
220

mains
but
can
be
supplied
with
a
switchable
motor
for
use
on
115,
145 and 225 V mains.
To
ensure
perfect
running,
important
bearing
and
driving
points
should
be
cleaned
if
necessary
be-
fore putting
on the turntable.
The important
points
are: Turntable
spindle,
underside
of turntable,
mo-
tor shaft
and the rubber
surface
of the idler
wheel
(41).
A clean, dry, non-fluffy cloth should be used for
cleaning. Only if oil or grease spots are present
should the cloth be sparingly sprinkled with methy-
lated
spirits
or
carbon
tetrachloride.
(Benzine
must
not be used.) The turntable should now be placed
on the spindle and the rubber mat on the turntable.
Push the large, counterweight (1) on to the rear end
(30) of the pick-up.
Interchangeable Plug-in Heads
The L.78 is usually supplied with an empty plug-in
head, so that each user may select his own pick-up
cartridge. The empty plug-in head (11) is complete
with mounting screws for the popular, internation-
ally standard cartridges. If various cartridges are
