SCHEMATIC DIAGRAM 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    Rating electrical power : 
1
/
 4 
W in resistance, 
1
/
10 
W and 
1
/
 8 
W in chip resistance.
: nonfl ammable resistor.
 : fusible resistor.
 : 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 impossibillity.
: B+line.
: B-line.  
(Actual measured value may be different).
: signal path. (RF)
Circled numbers are waveform references.
