60. REPLACEABLE PARTS
61. Tables 4, 5 and 6 list parts in alpha-numerical
order of their reference designations. It is important
that you refer to the table that documents the
instrument being serviced. Cabinet parts for all
three amplifiers are listed in Figure 11. Figure 12
lists the parts that make up the Type N connector
used in amplifier options 010 and Oil.
62. ORDERING INFORMATION
63. To obtain replacement parts, address order or
inquiry to your local Hewlett-Packard field office
(see list at rear of this manual for address). Identify
parts by their Hewlett-Packard part numbers.
64. To obtain a part that is not listed, include:
a. Instrument model number.
b. Instrument serial number
c. Description of the part.
d. Function and location of the part.
