Gold coated pins to enhance connection over long term
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.
All parts are selected to the highest grade plus only highly experienced workers to assemble. Suggested burn-in time is 80-150 hours
