6S19P-V / 6C19P-B tube. Audiophile triode NIB
The 6S19P-V (6С19П-В) tiode is designed for operation as a regulator tube in electronic voltage stabilizers.
The 6S19P-V triodes is are miniature devices enclosed in glass bulb and are provided with a nine-pin base and an indirectly heated oxide-coated cathode.
The 6S19P-V 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.
All tubes new in box, military equipment and have "OTK" mark. Near equivalent: -- . The tube is manufactured by the Reflector, Saratov, Russia.
