• C : panel designation.
• U : B+ Line.
• 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.
no mark : POWER ON
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
