We have a bunch of the following vintage tubes : #'s 227 , 71 , 71A.
What we don't have is valid tube testing data to test the tubes on a
Triplett 3413-B tube tester. Would anyone have the correct settings to test these 3 tubes.Are Updated Triplett data sheets available somewheres that handles these types of 4 pin tubes ? We are also looking for tube adapter to test the older 4 pin tubes on a Hickok 6000A Test tester. Are these still available ? If so where do we get one.
Thanks,
Mike aka N2LBV |
