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: Note:

•All capacitors are in ∝F unless otherwise noted. (p: pF) 50 WV or less are not indicated except for electrolytics and tantalums.

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

•% : indicates tolerance.

•2 : nonflammable resistor.

•C : panel designation.

•A : B+ Line.

•B : B– Line.

•H : adjustment for repair.

•Power voltage is dc 14.4V and fed with regulated dc power supply from +12V and REM terminals.

•Voltage and waveform are dc with respect to ground under no-signal condition.

•Voltages are taken with a VOM (Input impedance 10 MΩ). Voltage variations may be noted due to normal produc- tion tolerances.

•Waveforms are taken with a oscilloscope.

Voltage variations may be noted due to normal produc- tion tolerances.

•Circled numbers refer to waveforms.

•Signal path.

F : AUDIO

for printed wiring boards: Note:

•X : parts extracted from the component side.

• : Pattern from the side which enables seeing.
