I tested Tubes in Marra's Drugstore. How about you?
In the 60's when the tv, radio or amplifier was on the fritz my Dad would remove all the tubes, put them in a shoe box and send me to the drugstore. The drugstore had a tube tester. Each tube had a number printed on it and I would look up the number on the chart. The chart told you where to set a bunch of levers and then you pulled down the "Good or Bad" lever.
The druggest would sell me replacement tubes and Dad did the rest when I returned.
That came to mind today because I read that Radio Shack's days may also be numbered.
