specified.
• A : B+ Line.
• 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 M ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
