6P7S (original box)

Description

The 6P7S tube output beam tetrode, designed for operation in line scanning output stages of TV receivers. This tube is not a direct 6BG6 clone, it is an octal modification of G-807 tube, which one was soviet clone of famous 807.

6P7S and 6BG6 tubes has the same pinout and nearly the same characteristics.

Near equivalent to tubes: 6BG6G(A), 6L50(V), G-807.
