Tubes Asylum Questions about tubes and gear that glows. FAQ |

I am trying to find out how to test 300B tubes on my Hickok 539A tester. The only info I could find doing a search suggested test data that is beyond the limits of the 539A.Specifically, the recommendation was "Here is the setting for 300B: fil 5.0, selectors JR-3200-0, bias 60, english 87 . Mutual conductance 4600."
The problem is that the 539A bias only goes up to 50. Can I use the maximum bias I can get and still have at least results that will let me compare tubes?
