6P3S-E (original box)

The 6P3S-E 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.
