Psvane WE274B

Chinese Psvane WE274B.

This is absolutely not one of, but just the best rectifier tube you've ever heard!
Our product 274B is the only one in the world which completely reproduces the engraved Western Electric 274B of 1940s. There is no any compromise in every procedure, including the material, structure, technology, and sound performance etc.

Compared to the HiFi274B, the WE274B is smaller in size (identical size as the orginal WE274B) while the Psvane HiFi274B is of the same size as an average 300B tube. For sound, HiFi 274B has nice top extension but balance of tonality is not comparable to the 1:1 Replica WE274B. You can choose between the two based on your budget.

274B is very similar with 5U4G and 5Z3P, which can be replaced by each other in many cases.
