6N6P = ECC99 = E182CC tube. Gold grid NIB
The 6N6P (6Н6П) double triode is designed for low frequency power amplification.
The 6N6P double triode are miniature devices enclosed in glass bulb and are provided with a nine-pin base, rigit leads and an indirectly heated oxide-coated cathode.
The 6N6P 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 mechanical loads: liner loads up to 100g, vibration loads up to 2.5g and single impact loads up to 500g.
The grid is wound with wire made 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: ECC99 and E182CC. The tube is manufactured by the Nevz, Novosibirsk, Russia.
