Re-organizing my library, here are suggestions for some old-time classics, from before my age, from the halcyon days of the great kings of old, from the days when America was great or w/e. Also they're all very cheap.
"Electron Tube Circuits", 1950
"Electric Transmission Lines", 1950
"Basic Electronics", US Navy technician training book, 1973
"Probability and Information Theory, with applications for Radar", 1955
"Introduction to Bessel Functions", circa 1960?
