6S53N-V Nuvistor Miniature Triode Tubes

Made in USSR. New, old stock

The tubes are never used. The lot for 2 tubes. 

METAL-CERAMIC LOW NOISE AUDIO TRIODE, GREAT FOR FOR RIAA PREAMPS-RF APPLICATIONS

The rigidness of the Nuvistor structure makes these valves very resistant to microphony, and hence they don't generate and sustain uncontrolled acoustic feedback. Along with low noise and low power this is a key reason why they have been used in microphones, and also in high-quality audio pre-amplifiers

High reliability , long life non less 5000 hours. Tubes have rhombus <> markings on them.

               Tubes by 1970s                  

High quality made for the military equipment.

Similar to the E1010
