Description

The 6F1P triode-pentode is designed for use as a heterodyne, high-frequency voltage converter and amplifier and in pulse circuits of television receiver scanning networks.

The 6F1P triode-pentodes are miniature devices enclosed in glass bulb and provided with nine rigit leads and an indirectly heated oxide-coated cathode.

The 6F1P 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 25 g.

All tubes new, military equipment and have "OTK" mark. Near equivalent: 6U8 and ECF82.
The tube is manufactured by the ORZeP, Orel, Russia.
