Note:
• All capacitors are in
F unless otherwise noted. pF:
50 WV or less are not indicated except for electrolytic.
• 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.
F
• : 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 by using RV501 ([) as indicated. (See page 9)
Note: The components identified by shading and
¡
mark are critical for safety. Replace only
with part number specified.
