SCHEMATIC DIAGRAMS INFORMATION
All capacitors are in µF unless otherwise noted. pF : µµF 50WV or 
less are not indicated except for electrolytics and tantalums.
All electrolytics are in 50V unless otherwise specifi ed.
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 : 5mm

 : internal component
 : panel designation and adjustment for repair
 : earth ground
 : earth-chassis
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 10M digital multimeter.
Voltages are DC with respect to ground unless otherwise noted.
Voltage variations may be noted due to normal production 
tolerances.
All voltages are in V.
S : Measurement impossibility.
: B+line.
: B-line.  (Actual measured value may be different).
: signal path. (RF)
Circled numbers are waveform references.
Divided schematic diagram:
 
Some schematic diagrams 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 theline is connected to Ref. 
No. 1 of A (1 of 3) and A (2 of 3) schematic diagrams.
TO A1/3,A2/3_1
