When we trained with the Ontario Regiment they used
19 sets in all their tanks and had about half a dozen sets
in their main building. All these sets had a power supply with
a direct feed from a 120 volt plug. You plugged them into the wall socket.
It looked like a normal power supply. I have seen one since then at a show many years ago. But not lately.
Keep looking. You'll get one.
