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 14-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 match tubes either by emissions (mA) or transconductance (mhos) and must be within 10%. I will usually give both readings and then a % of what would be considered a NEW average tube. I don't use minimum average readings because it is too vague and confusing for buyers. All my tested tubes are stored in individual white boxes or original boxes labeled with manufacturer, tube type, and test results. Shipped in heavy-duty cardboard boxes with plenty of packing material. 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 Valve-Tubes!
