: B+ Line.
• Power voltage is dc 1.5 V and fed with regulated dc power
supply from mic plug.
• Voltages are dc with respect to ground under no-signal
conditions.
• Voltages are taken with a VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
