6P42S = EL509 = 6KG6 tube. Output beam tetrode
The 6P42S (6П42С) output beam tetrode for use in output stages block Horizontal TV receivers, as well as in a variety of equipment widely used.
The 6P42S output beam tetrode are miniature devices enclosed in glass bulb and are provided with nine flexible leads and an indirectly heated oxide-coated cathode.
The 6P42S electorn tube output beam tetrode are resistant to ambient temperature from -10 to +55°C and relative humidity of 95 to 98% at +40°C, as well as to mechanical loads: vibration loads up to 2g and multiple impact loads up to 12g.
All tubes new, military equipment and have "OTK" mark. Near equivalent: EL509 and 6KG6. The tube is manufactured by the Svetlana, St. Peterburg, Russia.
