I am replacing some pilot lamps and dusting out my Eico 720. Took out the 
final tube and noticed it has a fairly deep dimple which is surrounded with 
a black spot. The sunk in spot is probably a fat 1/16" deep. The depression 
area is just under the size of a dime...gradually rolls off into the deep spot. 
The tube is a Sylvania 6146/8298A. I'm sure I didn't run it that hard, but 
previously, it musta had a hard life. Final loading and output still where it 
should be. It's going back in....
