� All capacitors are in µF unless otherwise noted. pF: µµF 50WV or less are not indicated except for electrolytics and tantalums. � All resistors are in and 1/4 W or less unless otherwise specified. � ¢ : internal component. Note : The components identified by mark ! or dotted line with mark !are critical for safety. Replace only with part number specified. � � Note : Les composants identifiés par une marque !sont critiques pour la sécurité. Ne les remplacer que par une pièce portant le numéro spécifié. � Power voltage is dc 4.5 V and fed with regulated dc power supply from external power voltage jack (J401). � Voltage and waveforms are dc with respect to ground under no-signal conditions. no mark : STOP ( ) : PLAY � Voltages are taken with a VOM ( Input impedance 10M ). Voltage variations may be noted due to normal production tolerances. � Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances. � Circled numbers refer to waveforms. � Signal path. : CD
