Photo Kasper Bergholt

Below you find a part of the tube collection Kasper Bergholt.

I'm a collector, archiver & photographer of a variety of American & European produced vacuum tubes that have seen use in audio product, for example 6CS7 tubes, 12AU7A's, 12HB7A',s, 6CJ3's and 6X5GT tubes Tubes that are used in Leben amplifiers are for the time being of most interest to me.

In addition to photographing and arching/documenting tubes on this site, I keep high-resolution archives for free, non-commercial use on Pbase, some of thich are added to Wikimedia for free use too, in addition to filling in the blanks for tubes that don't have an image associated with their listing.

Other hobbies are Tai Chi, Pu Erh tea, listening to music, for the time being I'm especially interested in Japanese recordings of a variety of artits and genres.
