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.
T-KT88-EH-X Vacuum Tube - KT88, Electro-Harmonix

T-6SN7GT-PSV Vacuum Tube - 6SN7GT, Classic Series, Psvane
The Psvane 6SN7GT is a high quality, medium gain, dual triode with an octal base. The Psvane 6SN7GT is an excellent preamp tube with a classic look and sound. The Psvane 6SN7GT works great in any 6SN7 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.
