DIAGRAMS
Note on Schematic Diagrams:
• 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 1/
specified.
• C : panel designation.
• A : B+ Line.
•Voltage and waveform are connected and measured in
the USB port of PC.
•Voltages are taken with a V OM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production tolerances.
•Waveform is taken with a oscilloscope. Voltage variations
may be noted due to normal production tolerances.
• Circled numbers refer to Waveforms.
• Signal path.
F : AUDIO
Note on Printed Wiring Boards:
• Y : parts extracted from the conductor side.
• b : Pattern from the side which enables seeing.
• Indication of transistor.
