Replaceable Electrical Parts
Section 7
Replaceable Electrical Parts
This section contains a list of the components that are replaceable for the
TSG-271. Use this list to identify and order replacement parts. There is a
separate Replaceable Electrical Parts list for each instrument.
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. Therefore, when ordering parts, it is important to
include the following information in your order.
HPart number
HInstrument type or model number
HInstrument serial number
HInstrument 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.
Using the Replaceable Electrical Parts List
The tabular information in the Replaceable Electrical Parts list is arranged for
quick retrieval. Understanding the structure and features of the list will help you
find all of the information you need for ordering replaceable parts.

List of Assemblies
The Mfg. Code Number to Manufacturer Cross Index for the electrical parts list
is located immediately after this page. The cross index provides codes, names,
and addresses of manufacturers of components listed in the electrical parts list.
Abbreviations conform to American National Standards Institute (ANSI)
standard Y1.1.
A list of assemblies can be found at the beginning of the electrical parts list. The
assemblies are listed in numerical order. When the complete component number
of a part is known, this list will identify the assembly in which the part is
located.

The component circuit number appears on the diagrams and circuit board
illustrations, located in the diagrams section. Assembly numbers are also marked
on each diagram and circuit board illustration, in the Diagram section and on the
mechanical exploded views, in the mechanical parts list. The component number
is obtained by adding the assembly number prefix to the circuit number.

Mechanical subparts to the circuit boards are listed in the electrical parts list.
These mechanical subparts are listed with their associated electrical part (for
example, fuse holder follows fuse).
Chassis-mounted parts and cable assemblies have no assembly number prefix
and are located at the end of the electrical parts list.
