Double miniature triode - ECC82 is necessary for amplifying the level of low-frequency signals and is used in a variety of vacuum tube equipment - multifunctional generators (blocking generators), radio receivers, televisions, multivibrators. The radio tube was made in the form of a glass, cylindrical bulb, in the base of which there are nine hard contacts, has a miniature design and weighs no more than 14 grams. The triode was mass-produced in Hungary under the trademark "Tungsram".
