Note on Printed Wiring Boards: � Y : parts extracted from the conductor side. � a : Through hole. � b : Pattern from the side which enables seeing. Caution: Pattern face side: (Side B) Parts face side: (Side A) Parts on the pattern face side seen from the pattern face are indicated. Parts on the parts face side seen from the parts face are indicated.

Common Note on Schematic Diagram: � All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytics and tantalums. � All resistors are in � and 1/ 4 W or less unless otherwise specified. � C : panel designation. � U : B+ Line. � Power voltage is dc 4.5 V and fed with regulated dc power supply from external power voltage jack. � Voltages and waveforms are dc with respect to ground in playback mode. no mark : CD PLAY � : Impossible to measure � Voltages are taken with a VOM (Input impedance 10 M�). 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. J : CD
