Note:
• All capacitors are in
µ
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

W or less unless otherwise
specified.
•
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 un-
der 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 M
Ω
).
• Circled numbers refer to waveforms.
• Signal path.
