Thanks you. Unfortunately, my tube tester does not have data for any of those equivalent or closely equivalent types listed. I acquired the tube in a collection Left behind when a friend died and I'm trying to help his wife dispose of them. Apparently this tube is somewhat rare and I have seen them selling for over $100 on ebay. I would feel better listing a tube that had been tested. I guess I could just make sure the filament has continuity
