I tested 57 Tubes on my 2 calibrated TV-7B/U tube testers. The recommended minimum value for these types of tubes is 50/50 (60%). They all tested good, with no shorts. The test results are written on all tubes.
After going 57/57 good ones, I stopped testing and other 36 look new and should be fine too. This item is in the category "Collectibles\Radio, Phonograph, TV, Phone\Radios\Parts & Tubes".The seller is "davidandrews-tubes" and is located in this country: US. This item can be shipped worldwide.
