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: â¢ All capacitors are in ÂµF unless otherwise noted. pF: ÂµÂµF 50 WV or less are not indicated except for electrolytics and tantalums. â¢ All resistors are in â¦ and 1 /4 W or less unless otherwise specified. â¢ Â¢ : internal component. â¢ 2 : nonflammable resistor. â¢ C : panel designation. Note: The components identified by mark ! or dotted line with mark ! are critical for safety. Replace only with part number specified. â¢ U : B+ Line. â¢ V : Bâ Line. â¢ Voltages and waveforms are dc with respect to ground under no-signal (detuned) conditions. no mark : FM
â¢ Voltages are taken with a VOM (Input impedance 10 Mâ¦). Voltage variations may be noted due to normal production tolerances. â¢ Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances. â¢ Circled numbers refer to waveforms. â¢ Signal path. F : FM
For printed wiring boards.
Note: â¢ X : parts extracted from the component side. â¢ b : Pattern of the conductor side. Caution: Pattern face side: (Conductor Side) Parts face side: (Component Side) Parts on the pattern face side seen from the pattern face are indicated. Parts on the parts face side seen from the parts face are indicated.
