• U : B+ Line.
• Power voltage is dc 4.5V and fed with regulated dc power
supply from external power voltage jack (J401).
• Voltages and waveforms are dc with respect to ground
under no-signal conditions.

: Impossible to measure
• 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-
