Up for auction is this very nice very strong testing match pair of dark glass Raytheon 6SL7 audio tubes.  Both tubes would make a super nice addition to anyone's collection or to use either one, this. Both tubes were tested on my TV-7 tester where 32 is the required minimum and both tubes had no leaks or shorts.  Please, look at the above pictures for test scores as well as the overall cosmetic condition of this tube.  Thanks For Looking!
