My great-uncle's Zenith served him well, requiring only one major repair--the CRT screen cracked diagonally after only six months, probably due to a design flaw. However, the new CRT worked well until the day the set was replaced with a Zenith solid-state Chromacolor II 25-inch console several years later.
BTW: I'm not sure, but I think the set being discussed in this thread may be 100 percent tube powered. I believe the 1972 model of this set was all tubes as well. I don't know when Zenith went from all tubes to hybrids; may have been in the late '70s.

I believe '75 was the very last year that Zenith built a color TV using tubes. That particular model was a 4-tube hybird (horiz. output, damper, horiz osc, vert. output). The rest of the set was solid state.
