Note:
•All capacitors are in µF unless otherwise noted.
•All electrolytic capacitors are rated at 50V unless otherwise noted.
•All resistors are in ohms.
kΩ = 1000Ω, MΩ = 1000kΩ
•Indication of resistance which does not have rating electrical
power is as follows.
Pitch: 5 mm
Rating electrical power 1/4W (CHIP: 1/10W)
•: nonflammable resistor.
•¢: internal component.
•: panel designation or adjustment for repair.
•All variable and adjustable resistors have characteristic curve B unless
otherwise noted.
•Readings are taken with a color-bar signal input.
