6N14P = ECC84 = 6CW7 tube. Gold grid
The 6N14P (6Н14П) double triode is designed for use in amplification of high-frequency voltage.
The 6N14P double triodes are miniature devices enclosed in glass bulb and are provided with a nine-pin base and an indirectly heated oxide-coated cathode.
The 6N14P tube double triode 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 2.5g and impact loads pu to 35g.
The first grid is wound with wire made of an alloy of gold. The tube gives a very clean, warm and natural sound. Such a tube with a grid made of gold are very rare.
All tubes new, military equipment and have "OTK" mark. Near equivalent: ECC84 and 6CW7 . The tube is manufactured by the Reflector plant, Saratov, Russia.
