One pair of used but excellent condition 1998 re-issue Western Electric 300B vacuum tubes. These were part of factory matched quad. I have decided to keep a pair and sell a pair. The wooden box is not included in this sale but can be added for $50. They do come in their original individual boxes with original paperwork (warranty, test report, etc.).
These tubes were recently tested on a calibrated Heath TT-1 tube tester. If you are not familiar with the TT-1, it's a top tube tester as good as any TV7, Hickok, etc. Here are the serial numbers and test results where 1190 is the minimum GOOD level on the TT-1:
Those are like new test results! At my asking price, I will include everything - expert packing, domestic USPS Priority Mail shipping, insurance and PayPal fees. Please contact me for shipping outside the USA. Thanks!
