6N5S (original box)

The 6N5S (6H5C rus.) double triode tube – with separate indirectly heated cathodes and low internal resistance. Designed to work as a control lamp in circuits of electronic voltage stabilizers. It can be used as a low-frequency power amplifier in output stages assembled according to a push-pull circuit. Works in any position. 

Equivalent tube: 6AS7G, ECC230, 6N13S
