5 in stock


Holy….. this is a rare find and probably the best WE403B/5591/6AK5/EF95/5654 you will find out there.

LM Ericsson had the licence from WE to produce an exact copy of the 403B, but they did even better. You will find the identical plate construction as in the WE403 but as you can see on the pictures, the Swedish engineers  added not only gold pins but also gold grids & posts, ruggedized the whole thing and turned the plates into longlife versions.

Result? Amazing! First impression: these sound different. Is this good or bad? After a few minutes you realize that these simply transport the pure music without all the noise and distortion other EF95/6AK5 come with. Truely impressive! So far the Telefunken 6AK5 were our favorites, this has changed….

Ericsson themselves recommended to give them some extended heat up time before putting them to work.
