Note :
•
All capacitors are in µF unless otherwise noted.
• pF : µµF 50WV or less are not indicated except for
electrolytic types.
• Indication of resistance, which does not have one for
rating electrical power, is as follows.
Pitch : 5mm
Electrical power rating : 1/4W
• Chip resistors are 1/10W
• All resistors are in ohms.
k = 1000 ohms, M = 1000,000 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 Volts.
• Readings are taken with a 10Mohm digital mutimeter.
• Readings are taken with a color bar input signal.
• Voltage variations may be noted due to normal production
tolerences.
.
• : B - bus.
• : RF signal path.
• : earth - ground.
• : earth - chassis.
