New Product ! Tung Sol 7189 Matched Quad
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.
The original 7189 valve production ceased in the early 1980s and vintage 7189 valves have become expensive and hard to find. In order to allow these fine vintage 7189 amplifiers and receivers to continue be used, the Tung-Sol 7189 tube has been reissued. The 7189 Tung Sol® reissue is built to the same specifications as the original 7189 Tung-Sol for the high fidelity and performance expected from the vintage 7189 amplifiers and receivers produced in the 1960s and 1970s.
Strongly committed to quality manufacturing, Tung-Sol valves have always been known for their reliability and great tone. Today’s new production Tung-Sol valves are constructed with the same commitment to quality and reliability. Tung-Sol tubes reflect the best in vintage Tung-Sol construction with unsurpassed tone and reliability. They are manufactured in Russia.
The matched quads come with a test certificate showing the anode current and Gm. Made in Russia
