6P3S

 The electron tube 6P3S (6П3С rus.) is an output beam tetrode with an octal base designed to operate in the output stages of low-frequency power amplifiers. It is used in the output single-cycle and push-pull cascades of low-frequency receivers and amplifiers. It can be used as a high-frequency generator, transmitters and other general purpose equipment. Indirectly heated oxide cathode. Works in any position. The 6P3S tube has an octal base (8 – pin).

Near equivalent to tubes: 6L6, 6L6GT, 6L6GC and 5881
