For us it was either Christmas '72 or '73. I think '72. It was a tube set when fully transistorized was pretty much the norm. It actually only lasted 2-3 years. Not a very reliable set nor a great picture. Either that, or we watched it way too much and it died to escape.
Cool. I think our first one we got just prior to "the fall TV season" in 1973. I recall the year because my oldest sister was a senior in HS when we got it. I remember watching first season of "Happy Days" in full-color. Heyyyy!
Our first color TV endured for quite a few years -- I can't remember the brand at this point. Our last non-portable B&W set was leftover from the era of cabinet-on-legs; the initial color unit was the classic, heavier-than-*** wooden-console style that requires four grown men to move it more than 4 feet.
