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 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. f · : internal component. · 2 : nonflammable resistor. · 1 : 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. · A : B+ Line. · B : B Line. · Voltage and waveforms are dc with respect to ground under no-signal (detuned) conditions. no mark : FM · 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 : FM/AM L : MD/TAPE g : VIDEO 1 J : CD c : VIDEO 2 for printed wiring boards: · X : parts extracted from the component side. f · : internal component. · : Pattern from the side which enables seeing.
