The Stovebolt Site Forums The Shop Area The Electrical Bay The Radio Bench Tube CB radio?

It's pretty quiet in here, so I figured I'd ask some questions. From reading, I see that CB's showed up around 1958. Now, were these early tube type CB's always 12v? Where there 6v units made? Or was this just a good time for the truck owner to change over to 12v. I would imagine these early CB would draw quite a bit of power.

Thanks in advance.
