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.

- Premium Grade matched right out of factory to serve outside of China market

- Interchangable with 300B family of tubes for output of 10w

- Suggested burn-in time 150-300 hours. Most changes happen in the first 150 hours.

MESS PLATE 300B 
 
Sophia Electric Princess 300B mesh plate
 
 
 

Sophia Electric S.E.T. Princess 300B mesh plate tube is the upper class model of the current 300B line (globe shape is still in production). This new tube is using the same 300B plate(as the globe 300B) with stronger plate structure learned from making the original princess tubes. It is a true 300B tube. It will work with all 300B amplifiers (Western Electric 300B direct replacement).

The glass enclosure was from the Princess 206 tube for its unmatched sonic beauty. The shape of glass enclosure does make a major difference. Just thinking of violin's shape, if it gets changed to triangle, the sound character of violin will change for sure.

Sophia Electric engineers have conducted many hours of audition and comparison. In the end the current shape of Princess tube glass enclosure is the most preferred choice sonically. It has more volume and more curved than the old ST. It is not the old ST came back rather it is a carefully crafted, researched new 300B model. The result is a 300B mesh plate tube with super clarity, low distortion and out of this world mid range fullness and liquidity. High frequency extension and sweetness is the first thing you would hear.
