About Shuguang:

Shuguang is the oldest and largest tube manufacturer in China and worldwide, established in 1958 by engineers educated and trained in the United States in the 1930-1940s. Shuguang’s vacuum tube production accounts for the world’s 60% total tube output nowadays, either under their own brand “Shuguang” or under OEM brands.

Generic Shuguang tubes come in clear glass enclosure. The ‘Shuguang Treasure’  series comes with carbon compound coating inside the tubes making them appearing to be ‘black bottle’. They were released in Dec 2008 to celebrate Shuguang’s 50th anniversary and technology advancement and first brought by Grant Fidelity to worldwide market outside of China by Grant Fidelity. We found the “treasures” for tube lovers!

About Psvane: 

After launching the 50 year anniversary Treasure series in 2008, a team inside Shuguang has been developing new additions to its high end tube line to include large power tubes and small preamp tubes. With venture capital from UK and countless testing by Treasure series’ original design team, a new series called “Psvane” (pronounced as ‘Pavane’ – the brand is created from the inspiration of the 17th century classic music dance) T-series was born in Aug 2010. The Psvane series is a further fine tuning over the Treasure series, and the brand is owned by a separate entity other than Shuguang Group itself. Since Nov 2011, Psvane brand has officially become independent from Shuguang and production has been removed from Shuguang. New Psvane Audio manufacturing facility was acquired from Guiguang Tube Factory and has been expanding over time. The latest tube series from Psvane is called TII series – with grey color carbon coating inside, referred as ‘grey bottle’.
