6J5P = 6AH6 = 6F36 = 6485 tube. Pentode
The 6J5P (6Ж5П) high-transconductance pentode has been designed for h.f. voltage amplification in electronic devices.
The 6J5P pentodes are miniature devices enclosed in glass bulb and are provided with a seven-pin base, rigit leads and an indirectly heated oxide-coated cathode.
The 6J5P pentodes are resistant to ambient temperature from -45 to +70°C and relative humidity of 95 to 98% at +25°C, as well as to vibration with an acceleration of (from 1 to 60Hz) 2 g.
All tubes new, military equipment and have "OTK" mark. Near equivalent: 6AH6, 6F36 and 6485.
The tube is manufactured by the Oktjbr', Vinnitsa, Ukraine.
