The informations on this website are mostly collected from ebay auctions, online forums, tube sellers' websites and other online resources.
My interest is to keep tube knowledge alive through a new generation of tube enthusiast, as the one who lived during the original tube era is slowly fading away. I am myself born in the '80s, after most of American and European companies had already stopped producing tubes.
As I am afraid informations about tube models and company may get lost, I collect them from multiple online sources. I try whenever possible to be fair and reference the source, but if you feel I've missed you, please let me know.
While I aim to shoot hi-quality photos of the few tubes I own, most of the others are collected from ebay auctions. If you happen to be the owner of some of the photos and you prefer them to be removed, please contact me.
