Pretty much mirrors my own experience. I built lots of valve stuff in
the early 60s, often with parts taken from scrapped TVs and radios. I
even built my own tape recorder based on a Brenell deck and their
published circuits.
In 1970 I went to Uni and found out we were the first year that would
not be taught valves.
