Up for auction is a lot of 3 Telefunken 12AX7 tubes. With grey plates, round getter, Germany. They have been tested on a calibrated TV7. Tested for mutual conductance with a min of 32/32. They test as follows 46/46 diamond 8 on bottom, 44/45 diamond 12 on bottom and 50/45 diamond 4 on bottom. I do combine shipping. Due to a divorce I had to open a new account. I was formally known as Harleybabe8574. I have been dealing with tubes for many years.

Both tested and matched on a professionally calibrated TV7U tube tester with the following results (50 is minimum)- Tube 1- 65/67 Tube 2- 68/64

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% 78.5/62 PC 13.693/62 PC 17.4 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.
