Parts List — Type 561 A
HOW TO ORDER PARTS
Replacement parts are available from or through your local Tektronix
Field Office.
Changes to Tektronix instruments are sometimes made to accommo ­
date improved components as they become available, and to give you
the benefit of the latest circuit improvements developed in our engineer­
ing department. It is therefore important, when ordering parts, to
include the following information in your order: Part number including
any suffix, instrument type, serial number, and modification number
if applicable.
If a part you have ordered has been replaced with a new or im­
proved part, your local Field Office will contact you concerning any
change in part number.
