Same as a 6DJ8/6922, but with double the filament current. Sorry I can't tell you how to do that on your Hickok.
Hickok 752 tube tester....
I believe I have the Hickok 752, although it does allow the testing of both triodes at the same time. Anyhow, I would like to test some 6N1P tubes but I cannot find any settings in my enclosed tube roll. Would anyone care to share the settings for this tube with me? Thank you for your help.
