5.3.1 VISUAL INSPECTION
This section contains instructions and information to assist in determining, by visual inspection,
the condition of the KLN 94’s major assemblies and subassemblies. These inspection procedures
will assist in finding defects resulting from wear, physical damage, deterioration, or other causes.
To aid inspection, detailed procedures are arranged in alphabetical order.
A. Capacitors, Fixed
Inspect capacitors for case damage, body damage, and cracked, broken, or
charred insulation. Check for loose, broken, or corroded terminal studs, lugs, or
leads. Inspect for loose, broken, or improperly soldered connections. On chip caps,
be especially alert for hairline cracks in the body and broken terminations.
B. Capacitors, Variable
Inspect trimmers for chipped and cracked bodies, damaged dielectrics, and dam-
aged contacts.
C. Chassis
Inspect the chassis for loose or missing mounting hardware, deformation, dents,
damaged fasteners, or damaged connectors. In addition, check for corrosion or
damage to the finish that should be repaired.
D. Circuit Boards
Inspect for loose, broken, or corroded terminal connections; insufficient solder or
improper bonding; fungus, mold, or other deposits; and damage such as cracks,
burns, or charred traces.
E. Connectors
Inspect the connector bodies for broken parts; check the insulation for cracks, and
check the contacts for damage, misalignment, corrosion, or bad plating. Check for
broken, loose, or poorly soldered connections to terminals of the connectors. In-
spect connector hoods and cable clamps for crimped wires.
F. Covers and Shields
Inspect covers and shields for punctures, deep dents, and badly worn surfaces. Al-
so, check for damaged fastener devices, corrosion and damage to finish.
G. Flex Circuits
Inspect flex circuits for punctures, and badly worn surfaces. Check for broken trac-
es, especially near the solder contact points.
H. Front Panel
Check that name, serial, and any plates or stickers are secure and hardware is
tight. Check that the handle is functional, securely fastened, and handle casting is
not damaged or bent.
I. Fuse
Inspect for blown fuse and check for loose solder joints.
J. Insulators
Inspect insulators for evidence of damage, such as broken or chipped edges,
burned areas, and presence of foreign matter.
K. Jacks
Inspect all jacks for corrosion, rust, deformations, loose or broken parts, cracked
insulation, bad contacts, or other irregularities.
