Description
These 6550 tubes test at 62/44 62/44 on my TV-7D tester (calibrated annually). New tubes should test 68/44 or higher. Tested for shorts, emission, gas and noise. Both dated 17 02 for January of 2017. These were used and test at above 90% of expected new. These are Russian reissues. See the pictures and ask questions. I do not accept returns unless the items are not as described. I’m in the process of listing thousands of tubes. If you want something in particular message me to see if I have it. Thanks!
