Here at Eurotubes we have turned the testing and matching of vacuum tubes into an art form. Since 1998 we have used "state of the art” and custom made equipment to insure that you get the absolute highest quality tubes possible. All of our products are crafted in this manner. It is our passion!
Please note that we do not sell tubes on ebay or amazon. Unfortunately we get a lot of phone calls and email from players who have ordered JJ tubes from amazon and ebay wanting technical help and warranty service. While we always give technical help we don’t warranty tubes not purchased from us. The vast majority of ebay and amazon sellers buy untested tubes wholesale and then retail them without testing them and without any knowledge of the product.
