7-1. NOTES FOR PRINTED WIRING BOARD AND SCHEMATIC DIAGRAM

Note on Schematic Diagram:

• 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 Ω and

W or less unless otherwise

specified.

•

: internal component.

• C : panel designation.

Note: The components identified by mark ! or dotted line

with mark ! are critical for safety.

Replace only with part number specified.

• U : B+ Line.

• H : adjustment for repair.

• Power voltage is dc 14.4V and fed from CD changer con-

troller.

• Voltages and waveforms are dc with respect to ground in

playback mode.

• 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.
