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 .
