But a brilliant stream of consciousness. There may have been transistors
in those radios that did nothing, but I distinctly remember there being
several transistors being used merely as diodes, with the collectors not
connected. I recall the smell of tube radios, with their phenolics and
waxes, and remember trailing Dad to the local drugstore to test tubes.
If a bad tube was found, the store manager appeared to open the cabinet
that the tester sat upon and, after fishing around inside for a few
moments, pulled out the replacement tube with a flourish.
How the flourish got into the cabinet in the first place has always
puzzled me.
