5-4. SCHEMATIC DIAGRAMS AND PRINTED WIRING BOARDS
N o t e :
•
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 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 10 MΩ digital multimeter.
•
Voltage are dc with respect to ground unless otherwise noted.
•
Voltage variations may be noted due to normal production tolerances.
