Line Magnetic led the redevelopment of the WE212E tube in partnership with a domestic manufacturer, aiming to revive its legendary performance using modern techniques. Recreating the 212E posed significant challenges, as the original was a military-grade tube made with rare and now restricted materials. Through detailed analysis and reverse engineering, the team attempted to replicate its composition. However, environmental regulations under RoHS rendered some materials obsolete, causing delays. With persistence, alternative materials were sourced from European suppliers, enabling the team to match the original’s performance while remaining compliant. After multiple refinements, stable and reliable 212E samples were produced.

The tube’s heavy glass stem, prone to breakage during transport, highlighted the need for structural updates. Line Magnetic worked with the manufacturer to reinforce the design without altering its electrical characteristics. The result was a more shock-resistant structure with significantly improved reliability.
