WE274B
The true value of PSVANE WE274B is to tell everybody:
Only the legend can surpass the legend.
Following the world's first Western Electric 300B, PSVANE renew the
work to a peak.
Four places (China, Hong Kong, Taiwan, and the United States) have
worked for 18 months simultaneously to revise the sound and
determine the nature. PAVANE is the sole new vacuum tube which in
the true sense inherits the romantic charm of Western Electric, but
only one tenth price of it.
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.
We master the exclusive information of the original design drawing
and sealed formula, and in full compliance with all the details of
its requirement, such as the temperature and humility of the
production chain and so on.
