MAINTENANCE
Wire Connections
When
connecting
tape
decks,
record
player
or
other
components
to
the
AU-101,
be
sure
to
use
shielded
wire.
The
use
of
an
ordinary
cord
or
vinyl
wire
may
cause
humming
and
buzzing.
The
length
of
the
shielded
wire
should
be
shorter
than
5
feet.
Be
sure
that
all
lead
wires
between
the
amplifier
and
components
are
properly
connected.
If
the
con-
nections
are
loose
or
in
touch
with
other
parts,
the
amplifer
will
not
function
properly,
may
pickup
noise,
and
even
breakdown
over
a
period
of
time.
Also,
be
sure
to
read
the
manufacturer's
instruc-
tions
for
any
component
before
connecting
it
to
the
AU-101.
The
shielded
wire
is
made
up
for
use
as
illustrated
below:

Power Fuse
Should the amplifier fail to operate and the power
indicator
fail
to
light
up
when
the
POWER
switch
is turned on, the probable cause is either a power
stoppage
or
a
blown
fuse.
To
check,
remove
the
AU-101’s
line
cord
from
its
a.c.
outlet,
turn
the
fuse holder on the rear panel counterclockwise.
and remove the fuse. If it is blown, replace it with
a new glass-tubed fuse of the same capacity (100~
L17V—2A, 220~240V—1.5A) after determining
and eliminating the trouble source that caused the
fuse to blow. Using wire or a fuse of a different
capacity as a stop-gap measure is dangerous and
should be avoided.
Voltage Adjustment
This plug has been set to the voltage of your area
prior to shipment. Ifthe amplifier is ever moved to
an area with another voltage requirement, this plug
must be changed to the proper voltage of the new
area. lo change, remove the cramp from the back
panel, remove the plug from the voltage socket you
nave been using, and plug the arrow head into the
appropriate voltage requirement of 100, 117, 220
or 240 volts.
Quick-Acting Fuses
If, after the POWER switch is turned on and the
power indica‘or lights up, neither channel operates
_ or only one operates normally, is either because one
or both quick-acting fuses have blown. In this case,
remove the line cord from its a.c. outlet and remove
the bonnet from the chassis to check to see if the
fuses are blown. If the fuses are faulty, replace them
with identical 1.5A fuses (supplied) after finding and
eliminating the source of trouble that caused them
to blow. The trouble is probably by short at the
output circuit or excessive input fed into the input
circuit.
A.C, Outlets
The AU-101 is provided with two A.C. outlets on
its rear panel. One outlet (marked SWITCHED) is
switched on and off by the POWER switch on the
front panel.
Caution: The maximum capacity of this outlet is
OOVA, and the other (marked UNSWITCHED) is
1SO0VA. Never use either beyond their rated
capacity. The voltage supplied by the AC outlets
is the same as the power supply voltage used.
