Television tube testers in grocery stores - when did they start becoming uncommon?

I have memories of helping my dad fix our old black and white Zenith TV. We'd bring a bag of suspect vacuum tubes from our tv to a local grocery or merchandise store and test each, one at a time, on a tube tester. The tester was the size of a small jukebox, with many different socket types. I remember you'd plug a tube in the proper socket, hit a button, and read a needle that said something like good-weak-bad. Replacement tubes were avaialble at the bottom compartment of the tester. Looking back, I'm amazed there was this widely available infrastructure that allowed a consumer to diagnose and replace electronics parts from their TVs.
When did these testers stop being commonplace in stores? I'm guessing very early 70s and most definitely later than 1968 (that's when we immigrated to the US) but my memory is very fuzzy.
