L. Potentiometers
Inspect all potentiometers for evidence of damage or loose terminals, cracked in-
sulation or other irregularities.
M. Resistors, Fixed
Inspect the fixed resistors for cracked, broken, blistered, or charred bodies and
loose, broken, or improperly soldered connections. On chip resistors, be especially
alert for hairline cracks in the body and broken terminations.
N. RF Coils
Inspect all RF coils for broken leads, loose mountings, and loose, improperly sol-
dered, or broken terminal connections. Check for crushed, scratched, cut or
charred windings. Inspect the windings, leads, terminals and connections for cor-
rosion or physical damage. Check for physical damage to forms and tuning slug
adjustment screws.
O. Terminal Connections Soldered
(1) Inspect for cold-soldered or resin joints. These joints present
a porous or dull, rough appearance. Check for strength of
bond using the points of a tool.
(2) Examine the terminals for excess solder, protrusions from
the joint, pieces adhering to adjacent insulation, and parti-
cles lodged between joints, conductors, or other compo-
nents.
(3) Inspect for insufficient solder and unsoldered strands of wire
protruding from the conductor at the terminal. Check for in-
sulation that is stripped back too far from the terminal.
(4) Inspect for corrosion at the terminal.
P. Transformers
(1) Inspect for signs of excessive heating, physical damage to
the case, cracked or broken insulation, and other abnormal
conditions.
(2) Inspect for corroded, poorly soldered, or loose connecting
leads or terminals.
Q. Wiring/Coaxial Cable
Inspect wiring in chassis for breaks in insulation, conductor breaks, cut or broken
lacing and improper dress in relation to adjacent wiring or chassis.
