5-4. SCHEMATIC DIAGRAMS AND PRINTED WIRING BOARDS
Note:
•
All capacitors are in µF unless otherwise noted.
•
All electrolytic capacitors are rated at 50V unless otherwise noted.
•
All resistors are in ohms.
k = 1000 , M = 1000k
•
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 M digital m ultimeter.
•
Voltage are dc with respect to ground unless otherwise noted.
•
Voltage variations may be noted due to normal production toler-
ances.
•
All voltages are in V.
•
: Cannot be measured.
•
Circled numbers are waveform references.
•
