4-4. SCHEMATIC DIAGRAMS
Note:
• The parts marked "#" on schematic diagrams are not mounted.
• 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.
• 5 : 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.
• All voltages are in V.
• Readings are taken with a 10 MΩ 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.
•
V
: B + bus.
•
: B – bus.

•
F
: Signal path.

• Divided schematic diagram
Schematic diagrams of A, BB, BC, M and U boards are divided
into several pieces. Information to where the line is to be connected
is printed at the end of each line.
For example, [ TO A1/3,A2/3_1 ] means the line is connected to
Ref. No. 1 of A (1/3) and A (2/3) schematic diagrams.
TO A1/3,A2/3_1
Ref. No.
