Description

This E-212 tube model is in stock at Linlai factory. It is available by ‘factory special order’ only – we do NOT stock it in our own facility in Canada in order to limit shipping and handling for this extra large sized tube.  Order will be drop shipped from factory to buyer’s address directly in most cases. 

 

This giant sized 212 tube is definitely the ‘king’ of vacuum tubes – This listing is for “factory’s most recent version with enhanced plate capacity”. Do not confuse it with previous version.  

Developed from the original Western Electric 212E, it has added many modern engineering enhancement for a superb triode sonic ecstasy.

• Filament design has been improved from top spring fastened to an overhung hooked design. It not only greatly improves sound quality, but also improved reliability for shipping and handling for this EXTRA LARGE tube.

 

• Venting holes are added to the metal plate to not only efficiently dissipate heat, but also reduce swirling electrons inside the tube – which will improve sonic resolution and details, and avoid ‘muddy sound’ as in previously released versions.

 

• The 4-post reinforcement structure for the filament and plates help with reliability and improve upon previous ‘mica plate style’ for a more lively sonic signature.

 

• Additional Linlai™ proprietary plate coating allows this latest version of metal plate E-212 to sustain plate heat dissipation up to a HUGE 200 watts, without any sign of red plating over a continuous 120-hr burn-in test at factory lab.
