This lot is for a known value NOS 6L6 tube used in the calibration process for a Hickok 533, 533A, 534, 600, 600A, 605, 800, 800A, 6000, 6000A, or TV-7 military Hickok or Hickok-based tube tester. PLEASE SEE MY FEEDBACK FOR THESE TUBES. This tube can also be used to gauge the measured value of another brand tester as a comparison with what a regular Hickok reads, but I have no other brand calibration information.
