WE274B (per each)
The true value of WE274B is to tell everyone: only the legend can exceed legend.
After WE300B, PSVANE WE274B will continue to shock the world and reach the peak;
It takes 18 months to correct and perfect the sound synchronization in China, Hong Kong, Taiwan and America, PSVANE is the only new vacuum tube that can inherit the Western Electric, the price is only one-tenth of the original tube.
It will be the best rectifier tube that you have ever listened, is the best, no one!
It is the only one that completely copied the lettering edition of Western Electric’274B in 40S, there is no any compromise in material, structure, craft, sound performance and all the links :
Holding the drawing and formula of the original factory that have been sealed for years, totally followed the original requirement at all details that including humidity and temperature.
