(1) Tested Unbranded 6JB5 Tube. Manufacturer unknown as the name has been wiped from the glass. Due to the numbering style my guess would be either GE or Zenith, but I cannot say for certain. See test results below. Tested on a calibrated Knight KG-600B tube tester with no shorts and no leaks where 50 is minimum pass/good with the following results: Unbranded 6JB5 = 86 ~ Please view all 3 photos ~
