I'm a user, collector, archiver and photographer of a range of vacuum tubes (valves in British English), for example driver-stage tubes such as the 6CS7, the 12AU7A, the 12HB7A, the 6CJ3 family of damper tube and 6X5GT and 5U3C rectifier tubes, and lastly, the 5881/6L6/6L6G and EL34 family of output tubes. No 300B and single-triode designs for me so far.

Being the satisfied owner of a Leben CS-600 tube amplifier in addition to an RS30-EQ RIAA, tubes used in these products, naturally, for the time being are 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 & Wikipedia, some of which 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. I use vintage Nikon & Zeiss gear.

Other hobbies are Tai Chi, gastronomy, Pu-Erh tea, listening to music, for the time being I'm especially interested in Japanese recordings (most of which are of sublime quality) -- through a Goldring cartridge and the Leben RS-30EQ RIAA -- of a variety of artists & genres and photography-based art featuring photos of vacuum tubes, most prominently in my 'Objects for an Ideal Home' series, in addition to reading, writing about and curating art.
