Description: NOS 6H7B-V (6Х7Б-В) Ten tubes in one lot.We ship via International Airmail from post office in Kyiv.Tracking number is provided. Double subminiature diode with indirectly heated oxide cathode of increased reliability and mechanical strength.Designed to work as a detector or a low-power kenotron. Dual diode 6X7B - designed to detect and rectify alternating current. It is used as a detector and AGC detector in superheterodyne receivers, in cascades of discriminators and a fractional detector in frequency modulation receivers. It can be used as a rectifier for powering equipment with low current consumption. Indirectly heated cathode.Works in any position.The case is glass subminiature with flexible leads.
