In 1959 Tung-Sol developed a premium, up-rated version of the 6BQ5/EL84 for use in industrial and military circuits. This tube was designated 7189. Due to its higher plate voltage rating and increased clean headroom, it became a favorite power tube for use in medium power stereo amplifiers and receivers made by H. H. Scott, Sherwood, Fisher, Lafayette, and many other hi-fi manufacturers. It was also used in high-end guitar amplifiers manufactured by Magnatone. Due to its increased ratings, it was considered as an upgrade for 6BQ5/EL84 amplifiers for increased performance and reliability.
