CONTRAST OF MISCELLANEOUS PARTS CONTRAST TABLE XR-A660SW/DDXJ, XR-A660EE/MLWXJ/EE and XR-A660/DLXJ/NC are constructed the same except for the following : Note: For ASSEMBLIES, refer to “CONTRAST OF PCB ASSEMBLIES”, “2. SCHEMATIC DIAGRAM” and “3. PCB CONNECTION DIAGRAM”. Part No. XR-A660 /DLXJ/NC Ref. No.Symbol and DescriptionRemarksMark XR-A660SW /DDXJ XR-A660EE /MLWXJ/EE NOTES:Parts marked by NSP and can not be supplied. The mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure to use parts of identical designation. Screws adjacent to mark on the product are used for disassembly. Reference Nos. indicate the pages and Nos. in the service manual for the base model. When ordering resistors, first convert resistance values into code form as shown in the following examples. Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%, and K=10%). 560 56 101561 .RD1/4PU 5 6 1 J 47k 47 103473 .RD1/4PU 4 7 3 J 0.5 R50 .RN2H R 5 0 K 1 1R0 .RS1P 1 R 0 K Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5.62k 562 1015621 .RN1/4PC 5 6 2 1 F RadioFans.CN 收音机爱 好者资料库 XR-A660SW, XR-A660EE 3 C5501Not usedNot usedCCSQCH220J50 C5502Not usedNot usedCCSQCH270J50 C5815Not usedNot usedCKSQYB103K50 D5594Not used1SS133Not used D5595Not usedNot used1SS133 R9996RS1/10S0R0JRS1/10S0R0JRS1/10S561J X5501 (6MHz)RSS1050RSS1050ASS7015 CONTRAST OF PCB ASSEMBLIES XWZ3056 and XWZ3048 are constructed the same except for the following : PRIMARY ASSY Part No. XWZ3048 MarkSymbol and DescriptionRemarks XWZ3056 H3H6Fuse ClipAKR7001Not used S1AKX7006Not used XWZ3095, XWZ3096 and XWZ3085 are constructed the same except for the following : DISPLAY ASSY Part No. XWZ3085 MarkSymbol and DescriptionRemarks XWZ3095XWZ3096 XWZ3155 and XWZ3049 are constructed the same except for the following : SUB TRANS ASSY Part No. XWZ3049 MarkSymbol and DescriptionRemarks XWZ3155 S2AKX7004Not used RadioFans.CN 收音机爱 好者资料库 XR-A660SW, XR-A660EE 4 A B C D 1234 1234 FM/AM TUNER MODULE (AXQ7062) RF AMP MIX AMP BUFFER IF AMP PLL FM +B SW SW DRIVE AM RF TUNING BLOCK OSC 2.
