Since it needs a 12V adaptor, (which is not even included
), I'm guessing it uses one of those cheap "modern" Black and White set chassis, which the continous manual tuners. You always see the 5" models, but they also have 10 or 12" models I see sometimes in resale stores...
Seems if they are selling sometihng like this, which probably wasn't cheap when new, thet could put in a color remote chassis, and you could turn off the color for that "vintage" look.
