Notes

Also written as 6Н13С in Cyrillic; the Latin transliteration 6N13S is used interchangeably in Western markets.
The Russian datasheet specifies typical parameters at a lower operating point (Va=90V, Vg=-30V) than Western 6AS7 datasheets (Va=135V or 250V). At Va=90V: Ia=76mA, gm=5.5 mA/V, ra<=460 Ω per triode.
Maximum ratings per triode: Va=250V (operating), Va=500V (momentary on cold tube), Pa=13W, Ia=130mA.
Grid circuit resistance must not exceed 1 MΩ. When used in compensator-type electronic stabilizers as a pass element, Rg may be up to 3 MΩ.
Rated for ambient temperature range -60 to +70 °C and relative humidity up to 98% at +20 °C. Guaranteed service life: 1000 hours.
