  1. Remember when stores had tube tester stations where you could test your tubes and they had drawers of tubes for sale?

    1. I remember them in my local Mom & Pop Hardware store. My dad had a manual that told him the tubes that controlled various aspects of the TV and he took them to the store. He'd come back with a new tube he was convinced caused the trouble, but he was usually successful about once out of 5 times.
