6P6S (original box)

The 6P6S (6П6С rus.) output beam tetrode tube in a glass shell with an octal cap. Designed to work in the output stages of low-frequency power amplifiers. The output tetrode 6P6S is used in the output single-stroke and two-stroke stages of receivers and low-frequency amplifiers.

Tetrode 6P6S analog of 6V6GT tube and near equivalent to tubes: 6V6,  6AY5
