I cannot help you with your green tube, but there is a little more data about the type of tube you are looking for in this thread: http://www.avsforum.com/avs-vb/showt...hreadid=305538 . You may want to contact VDC to see if they rebuild your CRT http://www.videodisplayprojection.co..._catalog.html. The Retrographics use a modified tube (liquid coupled) from the more common front projection 800/801 Barco. The good news is that there is less of a market of used Retrographics due to their size and weight so I suspect somebody someplace has parted one out for the electronics and may have a spare tube lying around.
