Replaceable Electrical Parts - Tektronix 2246 1Y Service Manual

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, if any, is located at the rear of this
manual.

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

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:

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 numerical 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 Electrical Parts List.

Column three (3) indicates the serial number at which the
part was first used. Column four (4) indicates the serial number at
which the part was removed. No serial number entered indicates
part is good for all serial numbers.

In the Parts List, an Item Name is separated from the
description by a colon (:). Because of space limitations, an Item
Name may sometimes appear as incomplete. For further Item
Name identification, the U.S. Federal Cataloging Handbook H6-1
can be utilized where possible.
