• Waveforms
– MAIN (SW) Board –
For Schematic Diagrams.
Note:
• All capacitors are in μ F unless otherwise noted. (p: pF) 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
speci fi ed.
• f : internal component.
•
2
: Non fl ammable resistor.
• C : panel designation.
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
• A : B+ Line.
• Voltages and waveforms are dc with respect to ground
under no-signal conditions.
no mark : POWER ON
• Voltages are taken with VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
• Circled numbers refer to waveforms.
• Signal path.
F : AUDIO
For Printed Wiring Boards.
Note:
•
X
: Parts extracted from the component side.
•
Y
: Parts extracted from the conductor side.
• f : Internal component.
• : Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
• Indication of transistor.

from the pattern face are indicated.
Parts on the parts face side seen from
the parts face are indicated.
Note: The components identi fi ed by mark
0
or dotted
line with mark

are critical for safety.
Replace only with part number speci fi ed.
