SECTION 1 DIAGRAMS
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 and 1/4 W or less unless otherwise specified. · 2 : nonflammable resistor. · 1 : fusible resistor. 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. · Voltages and waveforms are dc with respect to ground under no-signal (detuned) conditions. · Voltages are taken with a VOM (Input impedance 10 M). Voltage variations may be noted due to normal production tolerances. · Signal path. F : AUDIO
