New Tri-Element Vacuum Tube

Characteristics：

Vacuum tubes assimilate the advanced 12 layers of spattering deposition of trivalent technology,high borosilicate glass,gradual change of ALN/AIN-SS/CU selective complex absorptive coating.Ang these make vacuum tubes have high performance of absorptance and low reflection ratio.Through the interlayer,vacuum has a unique effect of thermo,with its temperature up to 380℃ of idle sunning,performing a strong heating ability.
