Ray Tubes SELECT 6SL7

SELECT 6SL7 The 6SL7 is a high-mu variant of the more common 6SN7. Like many tubes, it was used extensively for military purposes during World War II, but slowly fell out of use in the following decades. Starting in the 1970s, renewed interest from the Japanese tube audio scene eventually led to a resurgence in 6SL7 popularity.
