6-4. 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.
