STANDARD CIRCUIT DIAGRAM

n NOTE :
1. RESISTANCE IS SHOWN IN OHM.

K=1000, M=1000000

2. UNLESS OTHERWISE NOTED IN SCHEMATIC ALL CAPACITOR VALUES ARE EXPRESSED IN F 3. VOLTAGES READ WITH VTVM FROM POINT INDICATED TO CHASSIS GROUND USING A COLOR BAR SIGNAL
WITH ALL CONTROLS AT NORMAL LINE 230V AC VOLTAGE READINGS SHOWN ARE NORMAL VALUES AND MAY VARY +20% EXCEPT H.V
4. THIS CIRCUIT DIAGRAM IS A STANDARD ONE CIRCUIT PRINTED MAY BE SUBJECT TO CHANGE FOR PRODUCT
IMPROVEMENT WITHOUT PRIOR NOTICE.

n WARNING :

BEFORE SERVICING THE CHASSIS, READ X-RAY RADIATION, SAFETY PRECAUTION, AND PRODUCT SAFETY NOTICE IN SERVICE MANUAL.

n PRODUCT SAFETY NOTE :

COMPONENTS MARKED WITH ARE IMPORTANT FOR MAINTAINING. THE SAFETY OF THE SET AND SHOULD BE REPLACED ONLY WITH TYPES IDENTICAL TO THOSE IN THE ORIGINAL OR SPECIFIED ONE IN THE PARTS LIST. DONT DEGRADE THE SAFETY THROUGH IMPROPER SERVICING.
