5-4. SCHEMATIC DIAGRAMS AND PRINTED WIRING BOARDS

Note:
• All capacitors are in µF unless otherwise noted. (pF: µµF)
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.
f
• : nonflammable resistor.
Ï
• : fusible resistor.
¢
• : internal component.
p
• : panel designation, and adjustment for repair.
• All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.
e
• : earth-ground.
E
• : earth-chassis.
• All voltages are in V.
• Readings are taken with a 10 M 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.
• Circled numbers are waveform references.
s
• : B + bus.
S
• : B – bus.
m
• : Signal path.
