Note:
• All capa<:itors are in µ F unless otherwise noted.
pF : µµ F 50 WV or Jessi are not indicated except for
electrolytics,
•
Indication of resistance, which· doe.s not have one for
rating electrical power, is as follows.
Pitch: 5 mm
Rating electrical power 1 /4W
• All resistors are in ohms.
•
~
: nonflammable resistor.
•
~

•
~
: intemal component.
• C=:=] : panel ·· designation.
• All variable and adjustable resistors have characteristic
curve B, unless . otherwise noted.
• The components ·identified· by 8 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 !.iii. make the
necessary adj.ustments ihdicated. If results do riot meet
the specified value, change the component identified by
8 and repeat the adjustment until the specified value
is achieved. (Refer to. R500 and· R690 · adjust on page
17 and 18)
• When replacing the p.irt in below table be sure to perform
the related adjustment.
