Tung-Sol Lamp Works was founded in 1907 in Newark, NJ USA. The name Tung-Sol is a contraction of Tungsten or tungsten the element where the filaments in tubes and light bulbs are made and Sol what in Latin means sun. Advertising for Tung-Sol car bulbs Since the 1920s, Tung-Sol also started producing other electronic products, including electron tubes. Tung-Sol strived for perfection of its products by means of a manufacturing process under laboratory standards and strict quality control. The best known tube from Tung-Sol is the 6550 marketed in 1955 in response to the Genalex / Marconi KT88. The 6550 is a so-called 'beam tetrode' and can be found in amplifiers with a lot of power, for example in the Ampeq SVT bass amplifiers and Marshalls 50 and 100 Watt guitar amplifiers for the American market. Also in the heavy amplifiers of Audio-Research, from the rare and most sought-after Audio Research the D150 (introduced in 1975) to the Reference 600, the 6550 as standard power tube deployed.
