One of the most famous American Valve manufactures of all time. RCA was responsible for designing and manufacturing many important valves such is the 6V6GT, 6L6GC, 7027a and the super EL84 known as 7189.
RCA also pioneered many advances in manufacture such as the black plate coating and had a hand in helping GEC make the famous KT66.
These are the Original USA made RCA 5840 which is a special quality version of the EF732 pentode. These high quality sub miniature pentode are well known for their extremely low noise and low microphonics and are used in valve microphones.The 5840 valve is currently used in Telefunkens current production models of the AK47mkII and ELA M 260
5840 is electrically similar to the AC701K which was used in such microphones as the Neumann M49. They have very low noise and produce a very refined sound, hence why many manufactures are now using this valve.
5840 replacement tube for the Telefunken AK-47mkII and ELA M 260 microphones.
