6P15P = EL83 = SV83 tube. Output pentode
The 6P15P (6П15П) output pentode is designed for amplification of output video-frequency voltage in television equipment.
The 6P15P output pentodes are miniature devices enclosed in glass bulb and are provided with a nine-pin base and an indirectly heated oxide-coated cathode.
The 6P15P electorn tube output pentodes are resistant to ambient temperature from -60 to +70°C and relative humidity of 95 to 98% at +40°C, as well as to mechanical loads: vibration loads up to 2.5g and multiple impact loads up to 35g.
All tubes new, military equipment and have "OTK" mark. Near equivalent: EL83, SV83 and 6P1T. The tube is manufactured by the Reflector plant, Saratov, Russia.
