Gentlemen. Re: higher voltage circuits... would it be too difficult
to develop a power supply, maybe a linear type, that outputs two
different voltages for different parts of the radio? Specifically, what
if most of the rig was run with 13.8 v as it is now, but the PA and
other necessary PA-related components were run on, say 24 or 48 volts,
with all power tapped from different windings on the same transformer?
Might that assist manufacturers in minimizing the cost to convert to
higher voltage circuits, while maintaining some continuity - all working
toward a cleaner output, with minimal rework to the whole deal?

Audio amplifier designs that produce significant amounts of power all
have been using bipolar +/-36 volts to +/-56 volts for years. They for
the most part use switching supplies internal. No reason ham
transceivers can't follow suit. Even a +50 volt supply would be
preferable for a transceiver.
