C202: .01
JLF ceramic.
CAUTION:
There are both non-
polarized and polarized electrolytic
capacitors
in this kit. Nonpolarized
capacitors are marked NP , and
polarized capacitors have a positive
"
+"or negative"-" marking. Be sure
to use an NP capacitor when it is
specified
in a step. All other electrolyt-
ic capacitors will be
the polarized type.
NOTE: NP capacitors
can be installed
with either lead in either hole .

JLF NP electrolytic.
C204:
33 pF ceramic.
C205: 56
pF ceramic.
NOTE: When you install a polarized
electrolytic capacitor, always
match
the positive ( +) mark on the capacitor
with the positive ( +) mark on the cir-
cuit board OR match the minus ( -)
mark on the capacitor with th e minus
( -) mark on the circuit board.
