[Mobile-Portable] 28-volt power?

[DavidE Benedict]

****
I have explored & experimented & proved (but not prototyped) using an auto
alternator to produce the 50-60 volts necessary for a 500-600 watt desktop
Ameritron Amp. to mobile use.

I also conceived that the output circuitry of a 12vdc to 120vac Inverter
could possibly be modified to produce 60 AC to be rectified and filtered
for the same purpose.

Write me privately with your phone number and good contact times if you'd
like to talk w/ me about it.
