Most of the big makers offered "value-line" TV sets that used some tubes up through 74 or 75. There were only a handful of companies making solid state color sets in '70-RCA, Motorola, I guess Sony and maybe some other Japanese companies. Sylvania might have been the next. The last tube chassis TV is generally considered the GE portacolor; I think production may have officially ended around '77 but several people have reported seeing later production dates, even into 1980. I have also read of some el cheapo bw sets that used a tube hv rectifier being produced up until 80 or even later. As for radios/stereos, the only ones with tubes beyond about 68 would have been special high-end equipment, I believe. (you can still buy such creatures today)
