The 3CX3000A7 is a popular tube with the 27MHz mobile crowd over here
Phil.
They use 240-260A alternators without diodes, etc into a 3 phase xfmr.
Typical design for over the road "talking" uses a 3500VDC 1.5A xfmr
which is designed for a 14VAC primary. At highway speeds the output is
in the 5-8KW output range. The strange thing....we wont get into FCC or
linearity issues.... is that they are reliable. Once setup they run for
years.
