THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this, the necessary note is printed in each block.) 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. • % : indicates tolerance. • f : internal component. • 5 : fusible resistor. • C : panel designation. Note: The components identified by mark 0 or dotted line with mark 0 are critical 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. • A : B+ Line. • B : B- Line. • H : adjustment for repair. • Voltage is dc with respect to ground under no-signal (detuned) condition. no mark : STOP ( ) : REC < > : PB ∗ : Can not be measured. • Voltages are taken with a VOM (Input impedance 10 MΩ). Voltage variations may be noted due to normal produc- tion tolerances. • Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal produc- tion tolerances. • Circled numbers refer to waveforms. • Signal path. d : PB G : REC (DECK B) • Abbreviation CND : Canadian model. AUS : Australian model. SP : Singapore model. For printed wiring boards. Note: • X : parts extracted from the component side. • : Pattern from the side which enables seeing. • Transistor of "B" and "C" indication is omitted. • Indication of transistor BC E These are omitted WAVEFORMS - MAIN SECTION (3/4) - 1 4.4Vp-p 10MHz IC801 el EXTAL 13 13 TC-WE475
