MX99
CASE
2
If you are
using
the MX-99
with another brand of
FM
tuner, and you
find
that
maximum separation is
obtained with the
SEPARATION
control set somewhere
between
8 and
10,
you can
usually maximize high-
frequency
separation
by
increasing the value of
C25
to
as much as twice its present
value of
.
OOlmfd.
(You
may do this
by
soldering
an additional
10%
disc
capaci-
tor in parallel
with
C25.
Try 470mmf first
and stick
with this value
if separation is noticeably
improved;
if not, try
.
OOlmfd).
NOTE: In Case
1,
the results of
removing
C25
are
favorable in all respects. In Case
2,
the increase in the
value of
C25
over its
present value of .001 mfd
will result in
a
somewhat higher background noise
level.
The
latter effect is not related to the per-
formance of the MX-99
Adaptor, but
merely
reflects
the
actual signal-to-noise ratio
in the tuner
over
the
frequency band con-
taining the multiplexed signal.

EICO’s SERVICE POLICY
SERVICE CONSULTATION
If you are experiencing trouble
that
you cannot
diagnose
yourself,
you are invited to avail
yourself of
the
EICO
Service Consultation
Department. The con-
sultant handling
your inquiry will make
every effort to
diagnose the cause of your particular difficulty
based
on the information that
you provide. Please be
as
thorough as possible. Include
the following information
about your
unit:
a) Have you made
a
thorough
check of the wiring,
checking also
for
cold solder
joints, or acci-
dental shorting between parts,
or to chassis?
(Check to see whether
a
bare wire
or
lead ex-
tends
far enough to be shorted when the bottom
plate is put on).
b)
Have you
checked that the proper tube or trans-
istor is in
each socket, and also making proper
contact in
the
socket?
Are
all shields firmly
in
place?
c) Does
the trouble occur at
one
time
or one
operating situation, but not at another time
or
operating situation? Be as specific as possible
in this respect.
d) If the
unit is
of
the
type that involves
alignment
or
calibration,
be as specific
as possible
as
to what you have
done or not done with
regard
to these requirements.
If the unit
incorporates
tuned
circuits stated
to be factory
pre-aligned,
did you change any
settings? If
so,
whatalign-
ment procedure did you
use?
e) Have you
observed any pecularity
about a
part?
If a part appears charred or otherwise
damaged
by
excessive heat,
please say so. If you think
you have damaged
a
particular
part in the
assembly or wiring, please
say so. In
con-
junction with the symptoms, the consultant
may
be
able
to determine whether
such a part is
likely to
be
defective.
f) Have
you gone through
any trouble-shooting
procedure
that may be provided?
If your manual
includes
a table
of contacts made at each switch
position, have
you checked
out the switches
accordingly
(if the trouble is
such that doing
this
would
be appropriate)?
Have you
been able
to make
checks of the operating voltages
and/or
resistances, if
this is appropriate,
and your
manual
provides
a
table
of voltages and
resist-
ances? What are the results of
these
checks?
Also,
have you taken any other
trouble-shooting
approaches? What have been the
results?
g)
If
this
is
high fidelity
equipment, please
state
the type
(magnetic, ceramic, crystal)
of phono
cartridge
you are using and/or the
make and
model
number. State the make
and model of
your record changer, or turntable
and
tone
arm.
Are the speakers in the same cabinet with
your
electronic
equipment? If
so,
describe
the
cabinet and the placement
of
the
components.
Please state the make and model
of your speak-
ers.
In addition, list
any code numbers
in
red under the
words
INSTRUCTION MANUAL
on the cover
of the
book provided with
your unit. If there are no red code
numbers,
state this
specifically.
If the unit bears a
serial number, it is essential
that you
include
this also.
PARTS REPLACEMENT
If it appears that a component is
defective, and
you desireareplacementfromEICO,
address your cor-
respondence to our Customer Service Department.
If you are claiming
the
right
to a no-charge re-
placement
under the terms and conditions of the war-
ranty,

at no charge
for parts

under
the terms
and
conditions of the
warranty. In returning tubes,

them very
carefully to avoid breakage
in shipment.
Broken tubes
will
not be
replaced. Please read
the
warranty on the subject of
parts eligible for replace-
ment.
Further
information required on a part returned
to the factory for a
no-charge replacement under the
terms and
conditions of the warranty is as follows:
a)
Model number and serial number, if any, of
unit. Also any code numbers in red
under
the
words
INSTRUCTION
MANUAL on the cover of
the book supplied with the
unit.
b) Stock number and description of
part as
given
on
the
parts list. If the part is not listed (of
itself) in the
parts
list, it
means that the part
is integral with a sub-assembly.
If the sub-
assembly is not sealed, and the defective
part
is
definitely identified
and
easily
replaceable
(not more than two connections),
you may re-
quest
replacement
for the particular part.
If
the
sub-assembly
is
sealed, or
if
the defective
part
is
not
definitely
identified or is not easily
replaceable (more than two connections),
then
remove the sub-assembly and return
it
to
EICO
(less
any tubes)
for repair or replacement, if
your
unit
is in warrantee.
If
your unit
is out
of warrantee, you are generally advised to
order
a replacement
sub-assembly.
c) Describe
as
completely
as possible the nature
of the defect, or your reason for requiring
replacement.
