--Most people got up to change the channel on their TV's.--
Behind the TV, a box of extra tubes. On top of the TV, a pair of pliars or wrench to turn the channels and a screwdriver to adjust the colors.
LOL. Also every time the TV broke you pulled a bunch of vacuum tubes and took the to the shop to run through a tester. Occasionally you would hear about so poor guy who forgot to drain the power out of the TV before trying to pull tubes.
