For Schematic Diagrams.
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.
•
f
: internal component.
• C : panel designation.
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
• A : B+ Line.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
• Voltages and waveforms are dc with respect to ground in
service mode.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
no mark : DVD STOP

: Impossible to measure
• Voltages are taken with VOM (Input impedance 10 MΩ).
• Circled numbers refer to waveforms.
• Signal path.
