Western Electric 275 is one of the rare buried products in all the works of Western Electric Vacuum Tubes.
It's all because the company designed the tube with a 5 volt filament.However,Its sound performance is the best in 2A3 made by other factories.On the basis of keeping the sound characteristics of Western Electric 275,PSVANE changed the 5 volt filament to 2.5 volt and maintained the generality of 2A3.Except that,the two products are almost exactly the same in appearance,structure,material and workmanship.That again shows the concept of "Only the legend can surpass the legend".
