6-4. PRINTED WRING BOARDS AND SCHEMATIC DIAGRAMS
• 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 specified.
• All voltages are in V.
S : Measurement impossibillity.
: B+line.
v : B-line.
•
•
• All resistors are in ohms.
KΩ=1000Ω, MΩ=1000kΩ
• Indication of resistance, which does not have one for rating electrical power, is
as follows.
Pitch : 5mm
•
(Actual measured value may be different).
: signal path. (RF)
• Circled numbers are waveform references.
Rating electrical power : 1/ 4 W

in this basic schematic diagram have been
carefully factory-selected for each set in order to satisfy regulations regarding
X-ray radiation.
Should replacement be required, replace only with the value originally used.
, make the necessary adjust• When replacing components identified by
ments indicated. If results do not meet the specified value, change the component identified by
and repeat the adjustment until the specified value is
achieved. (Refer to R530 and R531 adjustment on Page 15.)
• When replacing the part in below table, be sure to perform the related adjustment.
• Readings are taken with a color-bar signal input.
• Readings are taken with a 10MΩ digital multimeter.
• Voltages are DC with respect to ground unless otherwise noted.
• Voltage variations may be noted due to normal production tolerances.
