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.
