Testing 6J1 6AK5 EF95 vacuum tubes on a Hickok 539B tube tester
This video shows testing of 6J1 and 6AK5 vacuum tubes on a vintage Hickok 539B tube tester. A typical quality test of vacuum tubes includes shorts/leakage, gas, and mutual conductance testing. The Hickok models 539B and 539C testers are considered among the best of the vintage Hickok tube testers that were produced. If you are interested in GE 5654W (which is a premium substitute for 6AK5 and 6J1), please follow this link to my amazon store. http://www.amazon.com/Matched-5654W-F...
