Description

The 6P1P(6П1П) output tetrode is designed for amplification of low-frequency power.

The 6P1P output tetrode are miniature devices enclosed in glass bulb and are provided with a nine-pin base and an indirectly heated oxide-coated cathode.

The 6P1P electron tube output tetrode 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 12g.

All tubes new, military equipment and have "OTK" mark. Near equivalent: EL82. And similar to the 6AQ5, EL90 and the 6V6. Because of a different pinout (a 9-pin base versus 7-pin base) than an 6AQ5/EL90.

The tube is manufactured by the Svetlana, St. Peterburg, Russia.
