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
important, 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
representative will contact you concerning any change in part
number.
Change information, if any, is located at the rear of this
manual.
