Specifications

Here is a lot of strong testing and closely matched metal 6L6 tubes. 7 of them are rigid military grade. 2X VT-115, 2X 1622, 3x CRC-6L6. The other two are standard 6L6 but may have been used in medical or other equipment as they have matching green dots on the orientation key. Two of the tubes are missing the orientation pin but function fine just make sure you insert them in the socket correctly. These have all been tested on my calibrated Hickok 752a and are performing perfectly and strong as new. Here are the results of the testing: VT-115 -575 VT-115 #2 -600 1622 -575 1622 #2 -550 CRC-6L6 -625 CRC-6L6 #2 -650 CRC 6L6 #3 -625 6L6 -550 6L6 -600 (Average minimum good reading for this tube on this tester=300)
