For continued protection against risk of fire, replace only with same type and ratingfuse(s). To reduce the risk of electric shock, leakage-current or resistance measurements shall be carried out (exposed parts areacceptably insulated from the supply circuit) before the appliance is returned to the customer.The DC voltage is an actual reading measured with a high impedance type voltmeter with no signal input. The measurementvalue may vary depending on the measuring instruments used or on the product.IC1D1D2(3/4)JK1(2/4)IC1D18D3D4Q14Q13Q1D6D7Q4Q3Q2D12Q10Q11Q12D11Q9Q8Q7D13D14CN4P1P2D5Q6Q5CN3SPEAKERCN2CN1D15CN7CN8CN9S1(Y) TYPE ONLY(K,P,E) TYPEUSED(Y,X) TYPEUSEDCN6CN5SW1POWER SWIC1: TL084CNIC2: TDA7293VQ1,3,4,6,8,9,11,13 : 2N3906Q2,7,14: 2N3904Q5: 2N5401Q10: MPSW06Q12: MPSW56D1-7,11,13,18 : 1N4148D12: 1N5246BD14: KBU4DD15: B30-1852-05SIGNAL LINEB LINEB LINEGND LINE(4/4)IC1(1/4)IC1SP1LINEINPUT4911108270PC422u25+C239KR13216571213141000PC347KR322KR20.068C733KR833KR70.018C90.068C810u25+C5R41K0.068C6180KR633KR510u25C10+1KR20220R171KR151KR211KR2315KR5310KR1810KR194.7u50C19+220R16R54 15K47u25C2010u25C21+10KR3122KR321KR304.7KR28R26 47KR25 47K+10KR2910KR2747u25C262.2KR4847u25C27+10KR509.1KR512.2K 1/4WR4947u25C28+1/4W1u50C25+10u25C24+R364.7K22KR3922KR40R43 22K47KR4422KR37R3847KR24 47K470 2WR476.8KR45470 2WR460.047C380.047C393300u50C293300u50C30C34 0.022+0.047C37123AC3GNDAC41234567812345678C31C321KR34100KR5268R333.9 2WR141C16RL121GNDAC3C1547u50351910461114122815713C3622KR1247u50C14+47PC13390R131KR102134213410KR4110K(B)VR1GRNGND2AC43AC31TFJW 056810432179N31L(K,P) : AC120V 60Hz50/60Hz: AC110-120V/220-240V: AC230V 50Hz: AC240V 50Hz(X)(E)(Y)2134TF5342T21768910MAIN TRANS.MAIN TRANS.T1230V115VF2T1.25AL 250V0.01C35F10.01C3312312AC CORDEUROPEEDESTINATIONCOUNTRYU.S.A.CANADAPXABB.YPKNONONOYESJWAUSTRALIAXT2AT2ALT1.25ALT1.25ALF1B+BBLKWHT+B+B+B+B+B+B+B+B+B+BBBBBBBBBBBBR1122K+B0.0470.0470.010.010.01C31,32YESNONONOC36-39R9 1K32IC2SW-39HTPOWER SUPPLY PCBMAIN PCBParts with exploded numbers larger than 700 are not supplied.
