• 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

4
W or less unless otherwise
specified.
• 2 : nonflammable resistor.
• C : panel designation.
• U : B+ Line.
• V : B– Line.
• Voltages are dc with respect to ground under no-signal
conditions.
no mark : AUDIO
• Voltages are taken with a VOM (input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
F : AUDIO
• Abbreviation
CND : Canadian
