THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
For Printed Wiring Boards.
Note:
•
: Internal component.
f
•
: Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
Caution:

Note:
• All capacitors are in μF 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
specifi ed.
•
: Internal component.
f
• A : B+ Line.
• Voltages are dc with respect to ground under no-signal
(detuned) conditions.
no mark : iPod
• Voltages are taken with VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production
tolerances.
• Signal path.
: iPod
O
•
: Uses unleaded solder.
