• 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

W or less unless otherwise
specified.
• C : panel designation.
For printed wiring boards.
Note:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
• b : Pattern from the side which enables seeing.
• : B+ Line.
• : B– Line.
• Voltages are dc with respect to ground under no-signal con-
ditions.
no mark : Power on
∗ : Impossible to measure
• Voltages are taken with a VOM (Input impedance 10MΩ).
Voltage variations may be noted due to normal preduction
tolerances.
• Signal path.
K : AUDIO
