Robert Gillespie's Vacuum Tube Collection
If you, like me, appreciate the sheer engineering genius and artistry of a vacuum tube - especially the special purpose types - then you'll want to peruse the extensive collection of Mr. Robert Gillespie. His vacuum tube gallery is hosted on the RadioMuseum.org website. He writes: "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 as I am now the curator of the Gerald Tyne Collection, author of 'Saga of the Vacuum Tube,' 1977." If you have a unique vacuum tube not already represented there, you are welcome to submit photos and information. There are 1,629 as of this writing.
Note: the entire series of "The Saga of Vacuum Tubes" articles can be accessed on the American Radio History website in PDF format. Below, I have take taken the time to list and link to each edition containing parts 1 through 22, along with the pages on which they begin.
