5-3. SCHEMATIC DIAGRAM
Note:
•
All capacitors are in µF unless otherwise noted.
•
All electrolytic capacitors are rated at 50V unless otherwise
noted.
•
All resistors are in ohms.
kΩ = 1000Ω, MΩ = 1000kΩ
•
Indication of resistance which does not have rating electrical
power is as follows.
Pitch: 5 mm
Rating electrical power 1/4W (CHIP: 1/10W)
•
: nonflammable resistor.
•
¢
: internal component.
•
: panel designation or adjustment for rrepair.
•
All variable and adjustable resistors have characteristic curve
B unless otherwise noted.
•
Redings are taken with a color-bar signal input.

•
Readings are taken with a 10W MW digital multimeter.
•
Voltage are dc with respect to ground unless otherwise
noted.
•
Voltage variations may be noted due to normal produc-
tion tolerances.
•
All voltage are in V.
