Description
The 6N8S double triode with separate indirectly heated cathodes, designed to amplify low-frequency voltage and work in relaxation circuits. It is used in preliminary cascades of low-frequency amplification, cascades of phase inverters, in various pulse circuits, in cascades of scanning television receivers and measuring equipment. Indirectly heated oxide cathode. Works in any position.
