Note:
• All capacitors are in µF unless otherwise noted.
pF: µµF 50WV or less are not indicated except
for electrolytic and tantalums.
• All electrolytics are 50V unless otherwise specified
• Indication of resistance, which does not have one for
rating electrical power, is as follows:
Pitch: 5mm
Rating electrical power 1/4W
• All resistor s are in ohms.
KΩ=1000Ω, MΩ=1000KΩ
• f nonflammable resistor.
• ∆ : internal component.
• p: panel designation and adjustment for repair.
• All variable and adjustable resistors have charac-
teristic curve B, unless otherwise noted.
• The components identified b y
been carefully factory-selected for each set
satisfy regulations regarding X-ray radiation. Should
replacement be required, replace only with the value
originally used.
• When replacing components identified by
necessary adjustments 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 R582 on pages 21 and 22).
• When replacing parts in the table below be sure to
perform the related adjustment.

Readings are taken with a color-bar signal input.
•
Voltage variations may be noted due to normal produc-
tion tolerance.
