4-3. SCHEMATIC DIAGRAM INFORMATION
Note:
• All capacitors are in µF unless otherwise noted.(pF:µµ F)
Capacitors without voltage indication are all 50V.
• Indication of resistance, which does not have one for rating
electrical power, is as follows.
Pitch: 5 mm
Rating electrical power 1/4W (CHIP: 1/10W)
• All resistors are in ohms.
• : nonflammable resistor.
• : fusible resistor
• ¢ : internal component.
•: panel designation or adjustment for repair.
• All variable and adjustable resistors have characteristic curve B
unless otherwise noted.
• All voltages are in V.
•: earth-ground
•: earth-chassis
• All voltages are in V.
• Readings are taken with a 10 MΩ digital multimeter.
• Readings are taken with a color-bar signal input.
•Voltage variations may be noted due to normal
production tolerances.
• ✽ : Cannot be measured.
• NO MARK : PAL
• Circled numbers are waveform references.
•: B +bus.
•: B –bus.
• k : signal path.
