ZX-Series

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

The coating has been redesigned to strategically located in the most needed area of the tubes, while leaving other parts of the tube glass transparent to enjoy the 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).
