3 3 SA-WX700 SECTION 1 GENERAL This section is extracted from instruction manual. - Location of controls SECTION 2 DIAGRAMS For Schematic Diagrams. Note: - 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 Ω and 1/4 W or less unless otherwise specified. - C : panel designation. THIS NOTE IS COMMON FOR SCHEMATIC DIAGRAMS. (In addition to this, the necessary note is printed in each block.) -A : B+ Line. - B : B– Line. -V oltages are dc with respect to ground under no-signal conditions. - no mark : Power on -V oltages are taken with a VOM (Input impedance 10 M Ω). V oltage variations may be noted due to normal production tolerances. - Signal path . F : AUDIO - Abbreviation CND : Canadian model Note: The components identi- fied by mark 0 or dotted line with mark 0 are criti- cal for safety. Replace only with part number specified. Note: Les composants identifiés par une marque 0 sont critiques pour la sécurité. Ne les remplacer que par une piéce portant le numéro spécifié. 2-1.
