Robert Gillespie, USA (Stati Uniti d'America) - Collezione valvole

Qui trovi una parte della collezione valvole di Robert Gillespie. I started collecting tubes when I was 10, they were like little pieces of artwork. My fascination with tubes took off when I found my first industrial tube in an old warehouse. I do enjoy the odd photocells and photomultipliers, anything built by hand and not by machine. Currently, my focus is on collecting anything pre-1925 from anywhere in the world - which has been greatly boosted with my acquisition of the Gerald Tyne Collection, author of "Saga of the Vacuum Tube", 1977.
