Always replace them with new ones. (The chip parts include resistors, capacitors, diodes, transistors, etc). The negative pole of tantalum capacitors is highly susceptible to heat, so use special care when replacing them and check the operation afterwards. 6. Cautions in handling flexible PCB Before working with a soldering iron, make sure that the iron tip temperature is around 270... Take care not to apply the iron tip repeatedly(more than three times) to the same patterns. Also take care not to apply the tip with force. 7. Turn the unit OFF during disassembly and parts replacement. Recheck all work before you apply power to the unit. - 2 - EXPLODED VEIW EXPLOD] ED VIEW PART LIST ITEM Description Mfr’s Part No. 1 Heat sink MH-MA7A235-6SXXX 2 Left Chrome Cover MC-M7A235L-2CXXX 3 Right Chrome Cover MC-M7A235R-2CXXX 4 Front Panel MC-M7A2CHF-20XXX 5 Rear Panel MC-M7A2CHR-20XXX 6 Left Mounting foot PB-MA7AXXL-C0LEG 7 Right Mounting foot PB-MA7AXXR-C0LEG 8 Front End Cap PB-MA7AXX0-CCBRK 9 Rear End Cap PB-MA7AXX0-CCBRK 10 Bottom Chassis MB-MA7A235-2SXXX - 3 - PRINTED CIRCUIT BOARD CIRCUIT DIAGRAM 1 REMOTE ВАТТ GND CIRCUIT DIAGRAM 1 PARTS LIST - 1 Part Number de sc Location qty CR-40091X0-VQS00 4P1NS RCA RCA1 1 CT-SOCKETO-3MA7A PWER TERMINELS 1 CT-SOCKETO-4MA7A SPEAKER TERMINALS 2 EC-C4220XO-D5050 CAP 22PF(D) CI 19,219,319,419 4 EC-C4680X0-J5050 CAP 68PF(J) C116-7,216-7,316-7,416-7 8 EC-E2107X0-M50A1 CAP 100UF/16 C20 1 EC-E2227X0-M63A1 CAP 220UF/16 C3,4,101,115,201,215,301,315,401,415 10 EC-E2476X0-M50A1 CAP 47UF/16V C22 1 EC-E2477X0-MA0A3 CAP 470UF/16 C17,18 2 EC-E4225X0-M50A1 CAP 2.2UF/50 C102,104,202,204,302,304,402,404 8 EC-E4475X0-M50A1 CAP 4.7UF/50 C6,14,111,120,211,220,311,320,411,420 10 EC-E6228XO-MA3B5 CAP 2200/35V C2,12,13,19,23-6,30,31,33,34 12 EC-M5102X0-J5590 C-CAP 0.001 C7,103,203,303,403 5 EC-M5103X0-J5590 C-CAP 0.01 C5,8,21,27,32,151,251,252,312,313,351,352,412,413,451,452, 17 EC-M5104X0-JA0A3 C-CAP 0.1 C 1,9-11,15,16,28,29,121,221,321,421,422 13 EC-M5223X0-J66A3 C-CAP 0.022 C108,208,308,408 4 EC-M5333X0-J82A1 C-CAP 0.033 C314,414 2 EC-M5472X0-J5090 C-CAP 0.0047 C106,206,306,406, 4 EC-M5473X0-J80A1 C-CAP 0.047 Cll 8,218,318,418 4 ED-R2502CO-HOOOO DIODE ESAC25-02C D12,25 2 ED-R2502NO-HOOOO DIODE ESAC25-02N Dl 1,24 2 ED-R40Q1XO-HOOOO DIODE IN-4001 D13 1 ED-R5401XO-HOOOO DIODE IN-5401 D6.26 2 ED-S4148XO-HOOOO DIODE IN-4148 D1-D5,7-10,14-23 19 ED-Z 15VXX0-H4744 ZENER IN4744 ZD1,2 2 EE-C23X5XO-10302 LED RED 3MM LED2 1 EE-C53X5XO-10302 LED GREEN 3MM LED1 1 EO-1MA7475-VXXX6 TRANSFORMER TI ,2 2 EO-VMA924X-V8025 CHOKE COIL MA9-24 LI ,L2 2 ER-CS001X0-VE010 SLR0.1 5WJ R(l, 2,3,4)37, {1,2,3,4)38, (1,2,3,4)58, (1,2,3,4)59 16 ER-HG15 3XO-HXXXX THERMISTOR 150K TH1 1 ER-OGÛ22XO-H2526 RES 2.2 1/4W R135.136,156,157,235,236,256,257,335,336,356,357,435,436,456,457 16 ER-OG1O0XO-HAO4C RES 10 IW R16,26,39,40,144,244,344,444 8 ER-OG101X0-H2526 RES 100 1/4W R12,13-15,27,28,30,37,38,41,42,43,122,123,125,126,222,223, 225,226,322,333,325,000,000,000,000,000 28 - 7 - PARTS LIST - 2 ER-OG 101X0-H5039 RES 100 1/2W R10E102,201,202,301,302,401,402 8 ER-OG102X0-H2526 RES IK 1/4W R10,11,127-129,227-9,327-329,427-9,346,446 16 ER-OG102X0-HA04C RES IK 1W R17 1 ER-OG 103X0-H2526 RES 10K 1/4W R(l,2,3,4)20, (.1,2,3,4)42, (1,2,3,4)43,35,115,117,315,317,349,449 19 ER-OG 1O4X0-H2526 RES 100K 1/4W R354.454 2 ER-OG 105X0-H2526 RES 1M1/4W R29 1 ER-OG 122X0-H2526 RES 1.2K 1/4W RJ 18,218,318,418 4 ER-OG 124X0-H2526 RES 120K 1/4W R 172,272,372,472 4 ER-OG 152X0-H2526 RES 1.5K 1/4W R 107,207,307,407 4 ER-OG 15 3XO-H2526 RES 15K 1/4W R31,141,241,341,441 5 ER-OG 154X0-H2526 RES 150K 1/4W R4,153,253,314,414 5 ER-OG 18 3XO-H2526 RES 1SK 1/4W R32.33 2 ER-OG 184XO-H2526 RES1S0K 1/4W R(l,2,3,4)47,353,353,452,453 8 ER-OG220X0-H2526 RES 22 1/4W 1 ER-OG221XO-H2526 RES 220 1/4W R351,451 2 ER-OG221XO-HB05F RES 220 2W R19,20 2 ER-OG222XO-H2526 RES 2.2K 1/4W R3,7,25 3 ER-OG22 3XO-H2526 RES 22K1/4W Rl,9,23 3 ER-OG272XO-H2526 RES 2.7K 1/4W R133,233,333,433 4 ER-OG273XO-H2526 RES 27K 1/4W R355,455 2 ER-OG331XO-H2526 RES 330 1/4W R134,234,334,434 4 ER-OG332XO-H2526 RES 3.3K 1/4W R 108,208,308,408,462 5 ER-OG333XO-H2526 RES 33K 1/4W R8,22,171,271,371,471 6 ER-OG392XO-H2526 RES 3.9K 1/4W R111,204,311,404 4 ER-OG470X0-H2526 RES 47 1/4W R130,131,230,231,330,3 31,430,431 8 ER-OG471XO-H2526 RES 470 I/4W R(l,2,3,4,)39,( 1,2,3,4)40,(1,2,3,4)60( 1,2,3,4,)61 16 ER-OG472XO-H2526 RES4.7K 1/4W R6,21,24,36,132,232,332,432 8 ER-OG473XO-H2526 RES47K 1/4W R109,110,209,210,309,310,409,410 8 ER-OG562XO-H2526 RES5.6K 1/4W R5 1 ER-OG68 2XO-H2526 RES 6.8K 1/4W R121,124,221,224,321,324,421,424 8 ER-OG68 3XO-H2526 RES 68K 1/4W R 103,203,303,403 4 ER-OG824XO-H2526 RES 820K 1/4W R34 1 ES-S23D29X-V0098 SWITCH SK23D39 SW1,2 2 ET-C1023XO-PYOOO TR KTA1023-Y Q9,21,25,26,27,39,51 7 ET-C1027X0-N Y 000 TR KTC1027-Y Q8,20,38,50 4 ET-C1266X0-PYOOO TR A1266Y 3,4,5,15,16,17,32,34,35,44,46,47 12 -...
