Old Tv Nut knows his history. I was told R.C.A. made so many round tubes , that was why it took so long to come up with the rectangular tube in 1965. We could of done it sooner but like you said patents & the fact that R.C.A. thought every body would come up pay $ 1,000 for a color set,made to many round tubes......frenchy, Like the first B & W TV they could make round tubes faster like oscilloscope tubes. So Color same way. They just added the flate top & bottom, well don't know why can anybody help ?
