6J2P = 6AS6 = 5725 tube. Pentode
The 6J2P (6Ж2П) high-frequency short-characteristic pentode has been designed for h.f. voltage amplification.
The 6J2P 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 6J2P 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 200Hz) 5 g.
All tubes new, military equipment and have "OTK" mark. Near equivalent: 6AS6 and 5725.
The tube is manufactured by the Svetlana, St. Peterburg, Russia.
