Description

The 6N8S double triode is designed for amplification of low-frequency voltage.

The 6N8S double triodes are enclosed in glass bulb and are provided with an octal base and an indirectly heated oxide-coated cathode.

The 6N8S double triodes are resistant to ambient temperature from -60 to +70В°C and relative humidity of 95 to 98% at +20В°C, as well as to vibration with an acceleration of 1.5 g.

Best Quality, the Sound is nice - authentic vintage tone

The accuracy of matching a pair no less ±95%. Matched with our HI-END tube tester L3-3.

All tubes new, military equipment and have "OTK" mark. Near equivalent: 6SN7, ECC32 and 6CC10.
The tube is manufactured by the NEVZ, Novosibirsk, Russia. Have date codes of 197x years.
