Note:
•
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.
•
: 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.
•
When replacing the part in below table, be sure to perform the related
adjustment.
•
All voltages are in V.
•
Readings are taken with a 10 M  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.
•
: Signal path.
