Is there some reason why you can't disconnect the anode or remove one
tube and test the other one in your amp then switch to the other
socket to test the second tube?  Basically run a two tube amp with one
tube at a time.  It seems to me the dud will be revealed that way.  Or
both will be good or duds.  Save $70 plus shipping.
