G'day all.

Found an interesting site called Russian Tubes http://www.russiantubes.com which has data for tons of Russian valve/tubes including TV camera tubes which are featured on this page http://www.russiantubes.com/tubes.php?r=17 . There are a load of camera tube types listed from the early iconoscope type to the image orthicon type to the vidicon type and the other rarer types. Anyone like me interested in old camera tubes will find this site very interesting!:)

The first one, L17, seems to be mislabeled as an image orthicon - should be image iconoscope or super-emitron, judging from the shape and high required lux level.
