Description

The 6J2P-EV (6Ж2П) high-frequency short-characteristic pentode has been designed for h.f. voltage amplification.

The 6J2P-EV 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-EV 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 600Hz) 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.

The first grid is wound with wire made of an alloy of gold and platinum. Grid lifting is Copper. The tube gives a very clean, warm and natural sound. Such a tube with a grid made of an alloy of gold and platinum are very very rare.
