Description: Here we have a nice looking original Mullard EL34 6CA7 brown base double OO getter vacuum tube. Tested at 100% gm. Tube #1 - XF2 B4H4 Tested on an Amplitrex for fixed and auto bias. The auto bias raises grid voltage until spec plate current output of tube is reached. This gives an idea of the life left in the tube. Here are the fixed bias results: Tube #1 - 101 ma 11800 uhmos Spec for a new tube is 100ma and 11000 uhmos. Tested 100% for both. Passed gas test. Auto bias shows tube has 100% life left.
