Description

The 6s19p triode is designed for operation as a regulator tu in electronic voltage stabilizers.

The 6S19P triodes are miniature devices enclosed in glass bulb and are provided with a nine-pin base, rigit leads and an indirectly heated oxide-coated cathode.

The 6S19P triodes are resistant to ambient temperature from -60 to +70°C and relative humidity of 95 to 98% at +40°C, as well as to mechanical loads: vibration loads up to 2.5g and multiple impact loads up to 12g.

Best Quality, the Sound is nice - authentic vintage tone

All tubes new, military equipment and have "OTK" mark. Near equivalent: no have.
The tube is manufactured by the Uljanovsk, Russia. Tube have Gold grid.
