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 MΩdigital 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.
•: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.
