4-1. NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
(In addition to this, the necessary note is printed in each block.)
PS board SP TM board MAIN board
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. � 2 : nonflammable resistor. � 5 : fusible resistor. � C : panel designation. Note on Printed Wiring Boards: � X : parts extracted from the component side. � b : Pattern from the side which enables seeing. � Indication of transistor.
Q BC E These are omitted.

PHONO board
NOTE: The components identified by mark ! or dotted line with mark ! are critical for safety. Replace only with part number specified. � � � � U : B+ Line. V : B� Line. H : adjustment for repair. Voltages and waveforms are dc with respect to ground under no-signal conditions. no mark: POWER ON 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. K: TUNER
