As far as tubes being used as the HV rectifier in TV's, I think it was the late '60's-early '70's before the solid state "stick" HV rectifier began to be used in B&W portable TV's. I've gone through my Sam's Photofacts and I've seen some portable B&W sets as recent as the early '70's that retained a tube HV rectifier. I had a late '60's 12" GE solid state B&W AC/DC portable that used a 1X2 tube for the HV rectifier.
Speaking of Motorola, I believe they made the first solid state large screen color set, the Quasar works-in-a-drawer, in '66 or '67. This set also used a tube HV rectifier, as did the RCA CTC40 ('69), and the early Sony color sets from the late '60's-very early '70's.
