I think you could do that, but the configuration would
need you to separate the 6 volt filament circuits from the
DC original DC wiring, and check to see that there are no
6 volt electrolytic filters, DC PTT relays, or even a feed for a carbon
microphone. You may have to arrange a rectifier and filters.
Now the problem is simpler, Your AC input to the vibrator
primary, to avoid the need for a new transformer will work.
Back to vacuum tube CB radio days, it was common to have
a dual voltage input, i.e. 12 Volt for car use, and 120 VAC
for home use. They were called mobile or fixed unit transformers.
This the power unit for the Raytheon TWR-2 which is one of
the first of that ilk that I repaired back then.
