Vacuum Tubes

The first electronic amplification of sound was done with Vacuum Tubes. We have pre-amp, power and rectifier vacuum tubes among other types in New Old Stock from the golden era of American & European manufacturing as well as current production tubes from today.

Vacuum Tube - 6L6GB, Clear Top, Classic Series, Psvane
The Psvane 6L6GB is a high quality beam power tetrode with an octal base. The Psvane 6L6GB is noted for its outstanding sound and is an excellent choice for both guitar and stereo amplifiers. The clear top construction is similar to the classic short bottle 6L6 tubes made by GE and RCA. The 6L6GB is similar to other 6L6/5881 tubes but with a maximum plate dissipation of 19W. 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.
