NOTE
(For printed wiring boards)
• b : Pattern from the side which enables seeing.
(The other layers’ patterns are not indicated)
• Through hole is omitted.
• Circled numbers refer to waveforms.
• There are few cases that the par t printed on diagram
isn’t mounted in this model.
• Chip parts.
(For schematic diagrams)
• All capacitors are in
µ
F unless otherwise noted. pF :
µµ
F.
50V or less are not indicated except for electrolytics and tantalums.
• All resistors are in ohms, 1/4 W (Chip resistors : 1 /10 W) un-less
otherwise specified.

• Caution when replacing chip parts.
New parts must be attached after removal of chip.
Be careful not to heat the minus side of tantalum capacitor, be-
cause it is damaged by the heat.
• All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.
• 2 : nonflammable resistor
• 5 : fusible resistor
•
C
: panel designation
•
f
: internal component.
• C : adjustment for repair.
• U : B+ Line
•
V
: B– Line
• Circled numbers refer to waveforms.
• Voltages are dc between measurement point.
• Readings are taken with a color-bar signals on Blu-ray disc.
• Readings are taken with a digital multimeter (DC 10M
Ω
).
• Voltage variations may be noted due to normal production toler-
ances.
