5-4. SCHEMATIC DIAGRAMS AND PRINTED WIRING BOARDS

Note:
• All capacitors are in µF unless otherwise noted.
•
All electrolytic capacitors are rated at 50V unless otherwise noted.
•
All resistors are in ohms.
kΩ = 1000Ω, MΩ = 1000kΩ
•
Indication of resistance which does not have rating electrical
power is as follows.
Pitch: 5 mm
Rating electrical power 1/4W (CHIP: 1/10W)
•
: nonflammable resistor.
•
¢
: internal component.
•
: panel designation or adjustment for repair.
•
All variable and adjustable resistors have characteristic curve B unless
otherwise noted.
•
Readings are taken with a color-bar signal input.
no mark : PAL
( ) : SECAM
[ ] : NTSC 3.58
« » : NTSC 4.43
•
Readings are taken with a 10 MΩ digital multimeter.
•
Voltage are dc with respect to ground unless otherwise
noted.
•
Voltage variations may be noted due to normal production
tolerances.
•
All voltages are in V.
•
: Cannot be measured.
*
•
Circled numbers are waveform references.
•
: B + bus.
•
: B – bus.
•
: signal path.
