A little bit about me and my valve testing business..... I started in the tube business as a small hobby in 2012 testing and selling a few small radio tubes. Now it has turned into a big hobby as I have sold 1000's and 1,000's of tubes to many happy customers. I personally inspect and fully test each tube and offer a 30-day unconditional 100% guarantee on all my tested tubes. I am not a store or full-time business, but I take great pride and care in what I do, and your satisfaction is my number one goal. I have two of the best tube testers ever made that I use to fully test tubes. The Amplitrex AT-1000 Digital tester and the Triplett 3444 (with digital plate current meter) Tube Analyzer are both mutual conductance testers that can test just about any tube ever made between the two of them and can test for shorts/leakage, noise, gas, emissions, and transconductance. I have an extensive back stock of tubes, so if you have a certain brand or type you are looking for, feel free to contact me. Thank you for choosing Valves-Tubes!
