Note:
• The parts marked “#” on schematic diagrams are not mounted.
• All capacitors are in
µF unless otherwise noted. (pF: µµF)
Capacitors without voltage indication are all 50 V.
• Indication of resistance, which does not have one for rating
electrical power, is as follows.
Pitch: 5 mm
Rating electrical power 1/4 W (CHIP : 1/10 W)
• All resistors are in ohms.
•
: nonflammable resistor.
• 5 : fusible resistor.
•
: internal component.
•
: panel designation, and adjustment for repair.
• All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.
•
: earth-ground.
•
: earth-chassis.
• All voltages are in V.
• Readings are taken with a 10 M
Ω digital multimeter.
• Readings are taken with a color-bar signal input.
• Voltage variations may be noted due to normal production
tolerances.
•
*
: Can not be measured.
• Circled numbers are waveform references.
•
: B + bus.
•
: B – bus.
•
F
: Signal path.
