For your consideration; The 5933 is a ruggedised military version of the 807. This is the same as an 807W. This is an excellent matched quad . These are within 5 % of one and the other . These are the test results for each tube. I do not guarantee that you will get the exact test results as I received . I will say on a decent tube tester these will test very good . I have tested these on a Calibrated TV7-U military tube tester . Paul Hart performed the calibration .Test scores are also converted to microhms . Tube 1 - 72 = 3600 Tube 2 -72 = 3600 Tube 3 -72= 3600 Tube 4 -72= 3600 These are a 5 pin and T-12 Bulb . These are from a collection purchased from a collector in his 90’s who wanted to ensure another person would get to use or display the tubes he had collected for the better part of his adulthood. Please excuse my spelling when mentioning conversion results . I do not have the original boxes . Will be housed in a repurposed box or a white box . These audio tubes have been tested for shorts , gas and the life test also performed. These test results support nos test designation. You receive the tubes in the images . These are an excellent source of power for your amplifier.
