1-1. NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC 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. (p: pF) 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. � 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. � Voltages are dc with respect to ground under no-signal (detuned) conditions. no mark : Power on � Voltages are taken with a VOM (Input impedance 10 M�). Voltage variations may be noted due to normal production tolerances. � Signal path. F : AUDIO

For printed wiring boards.
Note: � X : parts extracted from the component side. � Y : parts extracted from the conductor side. � : Pattern from the side which enables seeing.
