For schematic diagrams.
Note:
• All capacitors are in µF unless otherwise noted. (p: pF) 50 WV or
less are not indicated except for electrolytics and tantalums.
• All resistors are in Ω and

W or less unless otherwise specified.
•%: indicates tolerance.
• f : internal component.
• C : panel designation.
• A : B+ Line.
• Power voltage is dc 9 V and fed with regulated dc power supply
from external power voltage jack.
•Voltages and waveforms are dc with respect to ground under no-
signal conditions.
•Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production toler-
ances.
•Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production toler-
ances.
• Circled numbers refer to waveforms.
• Signal path.
F : ANALOG
J : DIGITAL
