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...
