NEC, JVC/Nivico, Panasonic, Toshiba and Sanyo all had tube sets here in the 60s - Sanyo and NEC doubly so, with Sears-badged NECs, and Sanyos rebadged for Sears and Channel Master. Sharp had some B/W sets, but I never saw a color, so I can't confirm.
The NEC sets had a huge power tranny - I used to save them from junker sets for a ham friend. They also had troublesome tapped power resistors that would corrode the connections right off. Clean up the connection, re-solder, and that was all it took to fix the set.
The JVCs I saw were botched jobs, with the UHF tuners being really oddball monstrosities. It was like the set was made first for the Japanese market, and a UHF tuner added on hastily to market them in the states.
