5-2. PRINTED WIRING BOARDS AND
SCHEMATIC DIAGRAMS INFORMATION
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 :
1 1 1
/ W in resistance, / W and
4 10
: nonfl ammable resistor.
: fusible resistor.
: internal component.
: panel designation and adjustment for repair.
: earth ground
: earth-chassis
All variable and adjustable resistors have characteristic curve B, unless
otherwise noted.
Readings are taken with a NTSC color-bar signal input.
Readings are taken with a 10M 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.

The symbol indicates a fast operating fuse and is displayed on the component
side of the board. Replace only with fuse of the same rating as marked.
