MDR-NC11A SECTION 4 DIAGRAMS
� Note for Printed Wiring Board and Schematic Diagram
Note on Printed Wiring Board: � X : parts extracted from the component side. � Y : parts extracted from the conductor side. � : Pattern from the side which enables seeing. (The other layers' patterns are not indicated.) Caution: Pattern face side: (Conductor Side) Parts face side: (Component Side) Note on Schematic Diagram: � All capacitors are in µF unless otherwise noted. (p: pF) 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. A : B+ Line. H : adjustment for repair. Power voltage is dc 1.5 V and fed with regulated dc power supply from battery terminal. Voltages and waveforms are dc with respect to ground under no-signal conditions. no mark : POWER ON ( ) : POWER OFF 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. F : LINE INPUT (POWER ON) J : LINE INPUT (POWER OFF)
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.
