I think the designers were using the best materials & technology

using or restoring these devices several decades beyond their expected
service life. Most radios were considered appliances. Contemporary
electronics, even cars for that matter, are not designed to remain in
use forever. I remember when my Dad bought a Mercury in 1965, his one
and only new car. What would the salesman have said if Dad had asked how
that car might be running some 40-odd years later? Dad is still alive,
bless his heart, but the car perished decades ago.

My Mom still drives a '68 Rambler, and my Dad drove a '65 Dodge Dart
up until he died a couple of years ago. The car is still on the road.
