6F5P = ECL85 = 6VG8 tube. Triode-penthode
The 6F5P triode-pentode is designed for operation in vertical sweep units of widely used television receivers.
The 6F5P triode-pentodes are miniature devices enclosed in glass bulb and provided with nine-pin base leads and an indirectly heated oxide-coated cathode.
The 6F5P triode-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 vibration with an acceleration of 12 g.
All tubes new, military equipment and have "OTK" mark. Near equivalent: ECL85 and 6VG8.
The tube is manufactured by the Oktjbr', Vinnitsa, Ukraine.
