I've been running through the checks for the Novus Omni laser after a water leak stopped play at DutchLEM; I have found that water is escaping from the tube assembly through the locking ring at the upper end of the tube. It's leaking at a very fast rate, so it appears there is a missing seal. Looking for photos or diagrams of the parts in this area. I know this is basically an Innova tube, but not sure if the cooling arrangement is the same, but any info would be appreciated.
