All capacitors are in µF unless otherwise noted. pF : µµF 50WV or less are not
indicated except for electrolytics and tantalums.
All electrolytics are in 50V unless otherwise specifi ed.
All resistors are in ohms. K = 1000, M = 1000K.
Indication of resistance, which does not have one for rating electrical
power, is as follows: Pitch : 5mm
Rating electrical power :

: nonfl ammable resistor.
: fusible resistor.
: internal component.
: panel designation and adjustment for repair.
All variable and adjustable resistors have characteristic curve B, unless
otherwise noted.
Readings are taken with a color-bar signal input.
Readings are taken with a 10MΩ digital multimeter.
Voltages are DC with respect to ground unless otherwise noted.
Voltage variations may be noted due to normal production tolerances.
All voltages are in V.
S : Measurement impossibillity.
: B+line.
: B-line. (Actual measured value may be different).
: signal path. (RF)
Circled numbers are waveform references.

When replacing components identifi ed by Y, make the
necessary adjustments as indicated. If the results do not meet
the specifi ed value, change the component identifi ed by X and
repeat the adjustment until the specifi ed value is achieved.
When replacing the parts listed in the table below, it is important
to perform the related adjustments.
