SECTION 6
DIAGRAMS
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 diagrams.
Note:
• All capacitors are in
µ
F unless otherwise noted. pF:
µµ

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.
•
5
: fusible resistor.
•
C
: panel designation.
For printed wiring boards.
Note:
•
X
: parts extracted from the component side.
•
Y
: parts extracted from the conductor side.
•
a
: Through hole.
•
: Pattern from the side which enables seeing.
•
A
: B+ Line.
•
B
: B– Line.
•
H
: adjustment for repair.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
• Voltages are taken with a VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal produc-
tion tolerances.
BD (CD) board
no mark : CD stop
BD (MD) board
no mark : MD stop
( ) : MD playback
TC board
no mark : FM
( ) : TAPE record
Other boards
no mark : FM
< > : CD stop
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
• Circled numbers refer to waveforms.
Note:
The components identified by mark
0
or dotted line
with mark
0
are critical for safety.
Replace only with part number specified.
• Indication of transistor
Caution:
Pattern face side:
Parts on the pattern face side seen from
(SIDE B)
the pattern face are indicated.
Parts face side:
Parts on the parts face side seen from
(SIDE A)
the parts face are indicated.
• Abbreviation
CH : Chinese model
HK : Hong Kong model
• Signal path.
