""""When I was growing up in the 50’s and 60’s, there were actual repair shops that did appliances, TVs, Radios etc. Just like “Emmett’s Fix-It Shop” on the Andy Griffith Show....................""""

That went at least into the 70s, and quick stop stores used to have a device that would test your TV vacuum tubes.

Brings back memories. Especially when you play a guitar through an old Fender Twin Reverb.
