The problem at the time was that Motorola was trying make a cheap TV (The GoldenView was the first TV to sell for under $200), and a transformer would have cost more than a ballast tube, though it would have saved us a lot of troble today, but I don't think that Motorola was thinking that far into the future. It seems that if they had put a little more thought into the tubes they used they could have made a series string set with no ballast, like the later sets, but tubes they needed to do that probably wern't created yet.
I think there were other 7" sets that used a power transformer (Admiral?).
