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.

no mark : PB

( ) : REC

• Voltages are taken with a VOM (Input impedance 10 MΩ). 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.
