Product Description

1.Vacuum tube feature:   

    The kind of vacuum tube assimilate the advanced 12 layers of spattering deposition of trivalent element technology, high quality borosilicate glass 3.3, gradual change of CU-SS-ALN/ALN selective absorption coating and make vacuum tubes have high performance of absorptance and low reflection ratio. Through interlayer, vacuum has a unique effect of thermal, with its temperature up to 380 degree of idle sunning, performing a strong ability.
