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 MΩ).
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.
