Details

This tube is a true 6SN7 equivalent and you can use it in place of 6SN7 tubes of various brands. It has identical specification as RCA 6SN7. Do not use it to replace NOS CV181 tube.
True “Treasure” as a result of Shuguang’s 50-years’ of expertise in vacuum tube design and production.

High Polymer Compound Carbon (HPCC) coating is for the first time used on vacuum tube production. Compared to traditional carbon spray technology, HPCC coating will allow greater concentration of electrons, enhance and maintain stability of the electron flow, maximize “secondary electron emission surpression” from the glass enclosure, in turn reduce effects of electron swirl which generates internal noises from the vacuum tube itself.

Improved vacuuming technology during production process to clear signal background, Key assembling process is manually completed by a small number of senior technicians with 30+ years of experience. 60 extra parts selection and matching processes are adopted to ensure premium quality tubes, compared to the Shuguang generic clear glass tubes.

Premium Grade matched right out of factory to serve outside of China market, Interchangable with 6SN7 family of tubes, suggested burn-in time 150-300 hours. Most changes happen in the first 150 hours.

Attention:The surface and parameter of the premium grade is better than classic grade.and premium grade tube is gift box packing, classic grade tube is paper box packing.
