Replaceable Electrical Parts

Column Descriptions

Component No. The component circuit number appears on the diagrams and circuit board (Column 1) 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.

The electrical parts list is arranged by assemblies in numerical sequence (A1,

 

with its subassemblies and parts, precedes A2, with its subassemblies and parts).

 

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.

Tektronix Part No.

Indicates part number to be used when ordering replacement part from

(Column 2)

Tektronix.

Serial/Assembly No.

Column three (3) indicates the serial or assembly number at which the part was

(Column 3 and 4)

first used. Column four (4) indicates the serial or assembly number at which the

 

part was removed. No serial or assembly number entered indicates part is good

 

for all serial numbers.

Name and Description (Column 5)

Mfr. Code (Column 6)

An item name is separated from the description by a colon (:). Because of space limitations, an item name may sometimes appear as incomplete. Use the U.S. Federal Catalog handbook H6-1 for further item name identification.

The mechanical subparts are shown as *ATTACHED PARTS* / *END AT- TACHED PARTS* or *MOUNTING PARTS* / *END MOUNTING PARTS* in column five (5).

Indicates the code number of the actual manufacturer of the part. (Code to name and address cross reference can be found immediately after this page.)

Mfr. Part No. (Column 7) Indicates actual manufacturer’s part number.
