Vacuum Tube - ECC83 / 12AX7, Classic Series, Psvane
The Psvane ECC83 is a high quality, high gain, dual triode. This tube has a noval base and is praised for its warm and complex sound. The Psvane ECC83 works well in any ECC83 / 12AX7 position.
The Psvane Classic Series is focused on the reproduction of popular vacuum tubes found in classic audio equipment. When designing the Classic Series, Psvane collected the most sought-after NOS tubes and analyzed each element of their construction, incorporating the most effective manufacturing techniques to produce stable tubes with excellent sound. Whether used in guitar amplifiers or hifi stereo systems, the Psvane Classic Series vacuum tubes excel in all applications.
Psvane has been producing high quality vacuum tubes since 2011. The Psvane team originally formed in Shuguang’s high-end tube division but eventually split off to form their own brand. Psvane has since acquired their own manufacturing facilities with the goal of improving the production and performance of vacuum tubes. Today they manufacture many top-rated tubes with more than 50 tube types available.

3 very microphonic tubes in a row. USELESS!
The pins are cut off square, rather than rounded or pointed, which means the tube won't go into the socket. The sharp edge of the pin cuts into the socket and the pin bends rather than slide in. I had to round the end of the pin with a file to get it to go in. The lower price isn't worth even the hassle of that. Besides, the silkscreen label on the glass rubs off quickly, especially because you have to handle the dang thing so much before it works. This is typical Chinese stuff that looks like the real thing but isn't the same.
It performs fine electrically, but the diameter of the glass envelope is too large. The standard tube shields that are commonly used for 12AX7 do not fit. Avoid this if your use case requires a tube shield.
Good sounding tubes. Filled the nine pin side of an old Bandmaster. Did a side by side with another one that had new JJ ECC83S. Indistinguishable. Did a frequency sweep 100 to 10Khz. Nice. They have the tall plates. The only reason I didn't give them 5 stars is the longevity is unknown. Very good for the price.
Nice quiet and good sounding tubes...
This is the Chinese 7025 formerly sold as a Sino item..Now its costs almost twice as much but isn't that the way of things these days, i am glad to see it in stock
