4-2. CIRCUIT BOARDS LOCATION

• All capacitors are in µF unless otherwise noted.
pF: µµF 50 WV or less are not indicated except for electrolytic and
tantalums.
• All electrolytics are 50V unless otherwise specified.
• Indication of resistance, which does not have one for
rating electrical power, is as follows:
Pitch: 5mm
Rating electrical power 1/4W (CHIP: 1/10W)
• All resistors are in ohms.
KΩ = 1000Ω MΩ = 1000KΩ
•: nonflammable resistor
•: fusible resistor
•: internal component
•: panel designation and adjustment for repair
•: earth-ground
•: earth-chassis
• All variable and adjustable resistors have characteristic
curve B, unless otherwise noted.
• All voltages are in Volts
• Readings are taken with a 10M ohm digital multimeter.
• Readings are taken with a color-bar signal input.
• Voltage variations may be noted due to normal
production tolerance.
• * : cannot be measured
•: B + Line
•----- :B − Line
•: Signal path
