Been seeing these tubes on ebay for a while, always looked pretty good.
Nice to see someone here that has fired one up!
Keep the pics coming, someday when I have a real workshop with some more power i'd love to get into these.
I have one of these as well, that I'm also building into a laser cutter. Had a few issues recently with packages getting lost in the chaos of floods/cyclones, but replacements are on their way and it should be running soon!
These tubes don't have the greatest of lifetime, but they certainly do work!
