These were tested when stored, and tested again on Sencore TC28 just before listing Any tube that was below 90% was disposed of originally. Photo of individual tube provided upon request Tubes may or may not be boxed. Shipping is via USPS mail with tracking and insurance. I am not a flipper, I have been an engineer for 45 years, and this is from my personal collection. I just dont restore vintage electtronics as often as I used to. Every tube has been tested on a Sencore tester that has been/is correctly calibrated. Every sale is tested again before shipment including emission, vibration, and shorts. Any tube marked unbranded mean the name is obscured, or has come off while cleaning. There has never been a manufacturer that doesnt put their name on a tube. No tube will be listed as NOS as there is very few ways to tell if a tube is used or new. With all tube ages, there is no such thing as new. Luck of the draw, you may get a NOS tube. Many listed are in original boxes and are likely unused. All purchases will receive a message with photo of tube being tested before shipment.
