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. � C : panel designation. � U : B+ Line. � Power voltage is dc 14.4V and fed with regulated dc power supply from ACC and BATT cords. � Voltages and waveforms are dc with respect to ground under no-signal conditions. no mark : POWER ON * : Impossible to measure � Voltage are taken with a VOM (Input impedance 10 M�). Voltage variations may be noted due to normal production tolerances. � Signal path. F : AUDIO
