John wants to look at the links page. Ken & Chris will want to too if they haven't seen it. Belgian collection of over 2000 vacuum tubes and lamps. =A0=A0 =A0 =A0 =A0 =A0 =A0 =A0http://bit.ly/LampsAndTubes Site is a bit disappointing as it has several pictures of groups of tubes - presumably most or all of his collection BUT no lower level access on more detail, which would have been easy enough to do. *** BUT *** His links, accessed at bottom of page are wideranging and superb. About 80 links to other related sites. http://www.lampes-et-tubes.info/links.htm Including eg, tube data sheet locator. It says: "A fabulous Web resource for finding data on 17,000 vacuum tubes and more than 22,800 substitutes." http://tdsl.duncanamps.com/ And much more.
