6N5P

The 6N5P (6Н5П rus.) double triode tube with separate indirectly heated cathodes, designed to amplify high-frequency voltage in automatic gain control circuits. 6N5P is used in radio engineering devices for general and special purposes.
Works in any position.

The Russian 6N5P is a close equivalent to the following tubes: 6AU7, 12AU7 (12.6V), 7AU7, ECC804, 12BH7(A), B729, 6GA8.
