3-2. 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 specified.
All resistors are in ohms. kΩ=1000Ω, MΩ=1000kΩ
Indication of resistance, which does not have one for rating
electrical power, is as follows:
/ W in resistance, / W and
1 1
4 10
: nonflammable 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 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.
