Product Introduction
TII series is about to be upgraded to ART SERIES. Based on PSVANE's new independent research and development of thumb tube series "Four Little Swans" kicked off - 12AX7S, 12AU7S, 12AT7S, EL84S. The conventional varieties of TII series will be greatly upgraded, and ART SERIES 300B, 845, etc. will redefine the benchmark of high-end vacuum tubes.
The equally eye-catching PSVANE ECC83, ECC82, ECC81, EL84 are about to be launched. These are the thumb tube series independently designed and manufactured in China. Their addition will upgrade to the classic series (CLASSIC SERIES) together with other HI-FI series partners.
12AT7-TII is double triode small size novel tube，it is used as voltage magnification in amplifying circuit and inverter drive push-pull amplifier.
