Power Supply CBA Top View CAUTION ! Fixed voltage (or Auto voltage selectable) power supply circuit is used in this unit. If Main Fuse (F602) is blown , check to see that all components in the power supply circuit are not defective before you connect the AC plug to the AC power supply. Otherwise it may cause some components in the power supply circuit to fail. 2.5A 250V Because a hot chassis ground is present in the power supply circuit, an isolation transformer must be used when repairing. Also, in order to have the ability to increase the input slowly, when troubleshooting this type of power supply circuit, a variable isolation transformer is required. CAUTION ! : For continued protection against risk of fire, replace only with same type 2.5A, 250V fuse. ATTENTION : Utiliser un fusible de rechange de même type de 2.5A, 250V. NOTE: The voltage for parts in hot circuit is measured using hot GND as a common terminal. 00 L1 1 10 J361 GND 1 20 C6 GND C1103 C1203 C653 D660 C619 3 J369 GP 00 C658 IC601 C618 C650 P-ON+21V J159 J162 P-ON+21V J364 GND C1218 L1103 JS1101 L1103short +B J266 GATE1 JS603 C1217 1 D110 C603 L1201 +B +B J157 R610 JS605 JS604 15 D650 J158 GATE2 D659 C606 P-ON+21V J265 C605 C611 P-ON+21V C652 Q601-Source J600 D608 11 R6 21 R1 D602 D604 J160 P-ON+21V 5 R1 1 D601 J601 Q601-Gate C624 C617 1 No.2 BOND BOND GND C1220 P-ON+21V J155 J156 P-ON+21V J170 VLED2 ILED2 J171 GP J365 GND C657 CN1201 GND J362 A J152 P-ON+21V J153 P-ON+21V B C D E J366 D658 D651 C1118 C1119 C1219 Q601 D1 1 20 L1203 J261 LDR1 J264 BL-SW D606 R605 D6 J256 J263 PWM1 CN1101 EN2 D653 6 J353 GND D65 01 L6 HOT D654 55 J354 GND J259 CDR1 19 R6 J163 AMP+13V C602 C655 J260 CFB1 J359 GND J255 PWM2 J167 ALL+3.3V C656 C663 GND D662 3 2 00 GP CN501 5 00 GP BA4GP0F0102 1 10-19 J267 J161 P-ON+21V BL-SW J358 GND J368 GND SA601 W N HI E UT TE RA L Mountain fold J350 1 C651 PROTECT3 J268 GND GND J370 GND GND J367 J351 J169 ILED1 J360 GND CFB2 J250 P-ON-H2 J252 C668 J352 COLD 60 TOOL NO.
