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
: non flammable 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 DVD reference
disc.
• Readings are taken with a digital multimeter (DC 10MW).
• Voltage variations may be noted due to normal production toler-
ances.
