• ¢ : internal component.
• A : B+ Line.
• C : panel designation.
• Power voltage is dc 6V and fed with regulated dc power
supply from external power voltage jack (J901).
• Voltages and waveforms are dc with respect to ground
under no-signal conditions.

• Voltages are taken with a VOM (Input impedance 10 M ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
• Circled numbers refer to waveforms.
