W or less unless otherwise
specified.
•%: indicates tolerance.
•
f
: internal component.
• 2 : nonflammable resistor.
• 5 : fusible resistor.
• C : panel designation.
• A : B+ Line.
• B : B– Line.
•Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
No mark : FM
•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.
• Circled numbers refer to waveforms.
• Signal path.
F : FM
J : CD (ANALOG)
c : DVD (DIGITAL)
