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, 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
~llustration is clearly marked with the assembly number.
Assembly numbers are also marked on the mechanical exploded
views located in the Mechanical Parts List. The com2onent
number is obtained by adding theassembly 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 o f t h e Electrical Parts List.
