Tested on a fully restored TV7-DU, by Dan Nelson, pictures of evidence for this included in the listing. It was restored and calibrated on October 21st 2021. Tubes are tested for shorts. PC= Plate Current DC= Date Code Please note, TV7 data minimum is equal to 60%. For example, (insert model number here) min value 60. If the tube tests at minimum 60, that is equal to 60%. The number over (/) is the minimum test data result as described in the TV7 DU tube testing manual. So 60/ (min) 60 = 60% triode 1 9.9/32 PC 1 triode 2 17.5/32 PC 1.9 I mark all my tubes, so please dont waste your time seeking to send me back your old dead tubes. All testers read differently. I have sought to have my tester as accurate as possible. I will not be giving partial refunds because you have received different test result. All tubes will be shipped well, an example of how I pack is pictured in the listing. (obviously these tubes are not included) I wont be lying on a customs form I combine shipping. If the tubes are of significant value, the postage will be extra due to insurance.
