THIS NOTE IS COMMON FORPRINTED WIRING BOARDS ANDSCHEMATIC DIAGRAMS.(In addition to this, the necessarynote 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 in-dicated except for electrolytics andtantalums.

• All resistors are in Ω and 1/4 W or less un-less otherwise specified.

• C : panel designation.• U : B+ Line.• Power voltage is dc 14.4V and fed with

regulated dc power supply from ACC andBATT cords.

• Voltages and waveforms are dc with re-spect to ground under no-signal condi-tions.no mark : POWER ON

* : Impossible to measure• Voltage are taken with a VOM (Input im-

pedance 10 MΩ).Voltage variations may be noted due tonormal production tolerances.

• Signal path.F : AUDIO

For printed wiring boards.Note:• X : parts extracted from the compo-

nent side.
