Sylvania JAN CHS 6SL7GT / VT-229
Military spec tubes made in the 1940's. Very rare find. These tubes have long bottles with black bases, black plates and bottom-getters. One of the top-five 6SL7s. Sounds similar to later production Sylvania with its large soundstage. Some tubes are labeled and boxed for Heintz and Kaufman. Matched pairs available.
