Note:
•
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.
•
f
: nonflammable resistor.
•
Ï
: fusible resistor.
•
¢
: internal component.
•
p
: panel designation, and adjustment for repair.
• All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.
•
e
: earth-ground.
•
E
: earth-chassis.
• The components identified by
[
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.
• When replacing components identified by
]
, make the
necessary adjustments indicated. (See page 3-1)
• When replacing the part in below table, be sure to perform the
related adjustment.
