5-4. SCHEMATIC DIAGRAMS AND PRINTED WIRING BOARDS

Note:

•All capacitors are in ∝ F 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. no mark : PAL

(	)	: SECAM
[	]	: NTSC 3.58

« » : NTSC 4.43

•Readings are taken with a 10 MΩ digital multimeter.

•Voltage are dc with respect to ground unless otherwise noted.

•Voltage variations may be noted due to normal production tolerances.

•All voltages are in V.

•* : Cannot be measured.

•Circled numbers are waveform references.

•								: B + bus.
•								: B – bus.
•								: signal path.
