PARTS ORDERING INFORMATION
Replacement
parts
are
available
from or through
your local
Tektronix, Inc
Field Office or representative
Changes
to Tektronix instruments are sometimes made
to
accommodate
improved components
as they become
available,
and to give
you
the
benefit of the latest circuit
improvements
developed
in
our engineering
department It
is
therefore
impor-
tant, when
ordering parts, to include
the following information
in
your order: Part number,
instrument
type or number, serial
number,
and modification number
if applicable
If a part
you
have ordered
has been replaced
with a new or
improved
part, your local Tektronix,
Inc Field Office or represen-
tative will
contact
you
concerning
any change in part number
Change
information, it any. is located

LIST
OF ASSEMBLIES
A list
of assemblies can
be
found
at the beginning of
the
Electrical Parts List The
assemblies are listedin
numerical order
When the
complete component number
of a part is known,
this list
will identify the
assembly in which the part is
located

and addresses of manufac-
turers of

COMPONENT NUMBER
(column one of
the
Electrical Parts
List)
A
numbering
method has been
used
to
identify
assemblies,
subassemblies and
parts Examples of
this numbering method
and typical
expansions
are
illustrated
by the following
Example

A2 R1234
Only the circuit
number will appear on
the diagrams and
circuit board illustrations
Each diagram and
circuit board
illustration
is clearly marked
with the assembly
number
Assembly numbers
are also marked on
the mechanical exploded
views located in the Mechanical
Parts
List The component
number
is obtained
by
adding
the assembly
number prefix to the
circuit number
The
Electrical Parts List
is divided and
arranged by
assemblies in numencal
sequence (e
g
,
assembly
A1 with its
subassemblies and parts,
precedes assembly A2 with
its sub-
assemblies
and parts).
Chassis-mounted parts have
no assembly number prefix
and are located
at the end of the Electncal
Parts List
TEKTRONIX
