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 Ω and 1/4 W or less unless otherwise specified.

•f : internal component.

•C: panel designation.

Note: The components identified by mark 0or dotted line with mark 0are critical for safety.

Replace only with part number specified.

•A: B+ Line.

•B: B– Line.

•Voltages and waveforms are dc with respect to ground under no-signal (detuned) conditions.

no mark : STOP

( ) : PLAY

•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. J : CD c : digital out

For printed wiring boards.

Note:

•	X	: parts extracted from the component side.
•	Y	: parts extracted from the conductor side.
•	x	: parts mounted on the conductor side.
•		: Through hole.
