THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is
printed in each block.)
for schematic diagram:
• All capacitors are in µF unless otherwise noted. pF: µµF
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in
Ω
and 1 /
4
W or less unless otherwise
specified.
• f : internal component.
• 2 : nonflammable resistor.
• 1 : fusible resistor.
•
C
: panel designation.
•
A
: B+ Line.
• B : B– Line.
• Voltage and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
no mark : FM
• Voltages are taken with a VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
• Circled numbers refer to waveforms.
• Signal path.
F
: FM/AM
L
: MD/TAPE
g
: VIDEO 1
J : CD
c : VIDEO 2
Note: The components identified by mark 0 or dotted line
with mark
0
are critical for safety.
Replace only with part number specified.
for printed wiring boards:
• X : parts extracted from the component side.
•
f
: internal component.
•
: Pattern from the side which enables seeing.
