3-3. SCHEMATIC DIAGRAMS AND PRINTED WIRING BOARDS

Note:

•	All capacitors are in µF unless otherwise noted. (pF: µµF)		• Divided circuit diagram
	Capacitors without voltage indication are all 50 V.		One sheet of B and Q boards are circuit diagram is divided into three sheets,
• Indication of resistance, which does not have one for rating electrical
			each having the code B-ato B-c. For example, the destination
	power, is as follows.
			ab1 on the code B-asheet is connected to ab1 on the B-bsheet.
	Pitch: 5 mm
			a b 1
	Rating electrical power 1/4 W (CHIP : 1/10 W)			Ref. No.
•	All resistors are in ohms.
				Circuit diagram division code
•		: nonflammable resistor.
•		: fusible resistor.
•	T	: internal component.
•		: panel designation, and adjustment for repair.
•	All variable and adjustable resistors have characteristic curve B, unless
	otherwise noted.
•		: earth-ground.
•		: earth-chassis.

•When replacing the part in below table, be sure to perform the related adjustment.

•All voltages are in V.

•Readings are taken with a 10 M digital multimeter.

•Readings are taken with a color-bar signal input.

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

• * : Can not be measured.

•Circled numbers are waveform references.

•: B + bus.

• : B – bus.

Note: The components identified by shading and mark ! are critical for safety. Replace only with part number specified.

Note: Les composants identifié s par un tramé et une marque ! sont critiques pour la sé curité . Ne les remplacer que par une piè ce portant le numé ro spé cifié .
