Details

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.

‘Super Alloy’ technology is for the first time used in constructing vacuum tube. ‘Super Alloy’ technology was invented and first used in aviation, aerospace, military and other high-tech area. After 3 years of testing under extreme conditions, Shuguang has successfully adopt such technology in vacuum tube constructing to achieve directional solidification and single crystallization, greatly improving the ability of electron emission and electron current stability.

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.
