PARTS ORDER1 NG 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 i n our engineering department. It is therefore impor-
tant, when ordering parts, t o 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 Officeor represen-
tative will contact you concerning any change i n part number.
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 i n the Mechanical Parts List. The component
number is obtained by adding the assembly number prefix t o the
circuit number.
The Electrical Parts List is divided and arranged by
assemblies i n 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.
Change information, if any, is located at the rear of this
manual.
