6-2. CIRCUIT BOARDS LOCATION
Note: The components identified by shading and mark B
are critical for safety. Replace only with part
nummber specified.
6-3. PRINTED WIRING BOARDS AND
SCHEMATIC DIAGRAMS
Note:
• All capacitors are in µF unless otherwise noted. pF: µµF
Capacitors without voltage indication are all 50V.
• 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: 5 mm
Rating electrical power: 1/4W(CHIP:1/10W)
• : nonflammable resistor.
• : fusible resistor.
•
Å
: internal component.
• : panel designation and adjustment for repair.
• All variable and adjustable resistors have characteristic curve B, unless
otherwise noted.
• : earth-chassis.
• The components identified by
C
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.
