ZX-Series

Linlai Global ZX series is the most up-to-date version of the previous popular Treasure-Z series / T-series (black bottle) and T II (grey bottle) series made by both Shuguang and Psvane in the past decade.

The tube interior coating has been redesigned to be strategically placed in the most needed area of the tubes, while leaving other parts of the tube glass transparent, so that listeners can enjoy the magic warm tube glow.

The Linlai Global ZX series is the right step-up if you have been using stock entry level tubes that come with your amplifier. ZX series are priced very competitively and tube reliability has been enhanced by the past learning curve since 2008 (when the first Treasure Z-series bottle tubes first launched).
