•
U
: B+ Line.
• Power voltage is dc 12 V and fed with regulated dc power
supply from J101 with 100
Ω
in series.
• Power voltage is dc 9 V and fed with regulated dc power
supply from external power voltage jack.
• Voltage is dc with respect to ground under no-signal
condition.

• Voltages are taken with a VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal produc-
tion tolerances.
