Visual Inspection, Cataloging, and Research: We start by assigning each tube with a unique inventory number, while visually inspecting it for damage under the intense bright lights of our DSLR to computer photo chamber. We research the tube type and other relevant information to pass on to you. Testing With Our Calibrated TV7/U: We test each tube with our calibrated TV7/U tube tester. We take pictures of the tube while it is being tested and of the test results. We then record the test results to pass on to you, to help inform your buying decision with concrete data. If we dont have the right equipment or knowledge to test the tube, we make note of that in the description to be fully transparent. We NEVER claim a tube is tested, when it is not!

Our “Bullet Proof” Packing and Shipping “Honest and thorough, top notch packing, beautiful product. Highly recommend.” – Yet Another eBay Buyer “Arrived faster than possible” – And Another eBay Buyer Please dont shoot the package with bullets to test it! Its not actually bullet proof, but all shipments receive our super paranoid, over the top, packing for safe delivery. It basically means we think about all of the things that might break the vacuum tube or tubes (order more than one at a time for combined shipping discount) in transit and we try to make things so well packed, that the package could survive a tumble off of a three story building. Dont test that one either. Hopefully, as hard as we try, the package will be able to survive a delivery driver having a REALLY BAD DAY!
