Description

Coaxial metal-ceramic tetrode, forced-air-cooled, for frequencies up to 300 MHz. Due to the low feedback capacitance c g1a the tube is also suitable for use in grounded cathode circuit. To achieve a long service life, the cathode is especially designed for operation with controlled heating power . The radiator and the terminals are of concentric design with the following diameters:
