When I was in high school I built Heathkits and Knight Kits. A SW radio, tube tester, VTVM, etc. And I've still got most of the stuff I built and they still work. The first color TV we had, back in the mid-70's, was a Heathkit (it's long gone).
The big electronics parts store in our area is Fry's Electronics. You could put all the Radio Shacks in SoCal inside the Fry's store in Anaheim and still have room left over for a couple of McDonalds.
