5-3. PRINTED WIRING BOARDS AND
SCHEMATIC DIAGRAMS
Note:
• All capacitors are in µF unless otherwise noted. pF: µµF
Capacitors without voltage indication are all 50V.
• All resistors are in ohms.
k = 1000 , M = 1000k
• Indication of resistance, which does not have one for rating electrical
power, is as follows.
Pitch: 5 mm
Rating electrical power: 1/4W(CHIP:1/10W)
• f
: nonflammable resistor.
• F
: fusible resistor.
•
¢ : internal component.
• p
: panel designation and adjustment for repair.
• All variable and adjustable resistors have characteristic curve B, unless
otherwise noted.
• E
: earth-chassis.
• Readings are taken with a color-bar signal input.
• Readings are taken with a 10M digital multimeter.
• Voltage variations may be noted due to normal production tolerances.
• All voltages are in V.
no mark : REC/PB
( ) : REC
< > : PB
• Circled numbers are waveform reference.
•
: B + line
V
•
: B – line.
V
P
•
: signal path.
Note: The components identified by shading and mark
B
are critical for safety. Replace only with part
nummber specified.
