SCHEMATIC DIAGRAMS AND PRINTED WIRING BOARDS
Note:
•
All capacitors are in
μ
F unless otherwise noted. (pF:
μμ
F)
Capacitors without voltage indication are all 50 V.
•
Indication of resistance, which does not have one for rating
electrical power, is as follows.
Pitch: 5 mm
Rating electrical power 1/4 W (CHIP : 1/10 W)
•
All resistors are in ohms.
•
:
nonflammable resistor.
•
:
fusible resistor.
•
¢
:
internal component.
•
:
panel designation, and adjustment for repair.
•
All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.
•
:
earth-ground.
•
:
earth-chassis.
•
All voltages are in V.
•
Readings are taken with a 10 M
Ω
digital multimeter.
•
Readings are taken with a color-bar signal input.
•
Voltage variations may be noted due to normal production
tolerances.
•
*
:
Can not be measured.
•
NO MARK: PAL
•
Circled numbers are waveform references.
•
:
B
