Power Cable
- The power cable consists of three conductors. Two of
these conductors carry power to the instrument while the third conductor (green
wire)
is connected to the instrument chassis. The third wire projects from the
cable near the plug end of the cable and may be connected to
a ground when it is
desirable to have a grounded instrument chassis,

Tube Replacement
--
Any tube in this instrument may be replaced with a new tube having RMA
standard characteristics, without impairing the operation of the instrument.
Tubes with abnormal characteristics will usually cause poor regulation.
Voltage Control Adiustment
--
If the VOLTAGE CONTROL shifts so that it does not give a voltage range
of from 100 to 360 volts, adjustment of R23 and R24 will be necessary.
