Note:
• All capacitors are in µF unless otherwise noted. pF: µµF 50WV or less
are not indicated except for electrolytics and tantalums.
• All electrolytics are in 50V unless otherwise specified.
• All resistors are in ohms.
kΩ = 1000Ω, MΩ = 1000kΩ
• Indication of resistance, which does not have one for rating electrical
power, is as follows.
Pitch: 5 mm
Rating electrical power: 1/4W
• 1/4W in resistance, 1/10W and 1/8W in chip resistance.
•
: nonflammable resistor.
•
: fusible resistor.
•
Å ¢
: internal component.
•
: panel designation and adjustment for repair.
• All variable and adjustable resistors have characteristic curve B, unless
otherwise noted.
• Readings are taken with a color-bar signal input.
• Readings are taken with a 10MΩ digital multimeter.
• Voltages are dc with respect to ground unless otherwise noted.
• Voltage variations may be noted due to normal production tolerances.
• All voltages are in V.
