Up till now, PSVANE has been the lead and noble in the field of
tube sales. Not only had it been well received by users, but also
even some amplifiers at home and abroad has had upgraded to add
PSVANE as a selling point.
PSVANE always front in R&D of tubes. Till 2013, PSVANE has
accumulated the power to launch nearly 10 types of new items
constantly, and all types are the tops in market, which gained
numerous praises.
As the most promising products, three new items naming UK are ready
to have a grand listing.
UK-EL34, UK-KT88, UK-6SN7, which are PSVANE HI-FI series, have the
greatest cost performance that have never seen in history.
These are the items that PSVANE European R&D team has spent
nearly one year to produce. Having received constructional
dissection in many types of classical English and Swedish prototype
tubes that are the same size but were produced in different
periods, analyzed one by one and copied materials to ask the most
stability and greatest sound performance, even received many times
of revises of sound performance that across the ocean, our team
still hold the belief that has a sensitive feeling about products
as artists and be persistent like craftsmen, also keep the ancient
and precise handwork skill:
Three types of items all adopt the most English sound- tasted plate
material—“Mould Screen”, and all integrate with the symbolized
musicality and emotional attractiveness that PSVANE have, we
believe what you are going to get are the most sound-tasted tube
that are the same price;
With vintage style as prerequisite, having respected and followed
structural design and material use of the earlier classical same
size tubes, we preserve the original structure and sound
performance of three items.
To ensure the durability and detail transformation of our products,
we still use the gold-painting technology to base pin even in low
selling price.
