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
and 1/4 W or less unless otherwise
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 VOM (Input impedance 10 M
).
Voltage variations may be noted due to normal produc-
tion 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.
