List
Parts are
listed
by
ASSEMBLY,
then
by TYPE,
then
by

DESIGNATOR.
Widely
used
common
parts are
not
listed;
such
parts
are described generally
below (examine
the part
to
determine exact
value).
See
the
following
assembly drawings
for locations
of components.
SIGNAL
DIODES,
if
not
listed
by
reference designator
in
the
following
parts
list,
are:
Orban
part
number
22101-000,
Fairchild
(FSC)
part
number
1N4148,
also available
from
many
other vendors. This
is
a
silicon,
small-signal
diode with
ultra-fast
recovery and high
conductance.
It
may
be
replaced with

RESISTORS
should only
be
replaced with
the
same
style
and
with
the
exact value
marked
on
the
resistor
body.
If
the
value
marking
is
not
legible,
consult the
schematic or
the
factory.
Performance and
stability
will
be compromised
if
you do
not use exact replacements. Unless
listed
by
reference designator
in
the
following
parts
list,
resistors are:

Obtaining spare
parts:
Special or subtle
characteristics
of
certain
components
are exploited to
produce an
elegant
design
at
a
reasonable
cost.
It is
therefore
unwise
to
make
substitutions
for
listed
parts.
Consult
the factory
if
the
listing
of a
part includes the
note "selected"
or
"realignment
required".
Orban
normally
maintains
an
inventory
of
tested,
exact
replacement
parts that
can be
supplied
quickly
at
nominal
cost.
Standardized spare
parts
kits
are also available.
When
ordering
parts
from
the
factory,
please
have
available the
following information about
the parts
