    Here's the dead tube. Probably not caused by V3.

    That looks like a cracked tube. Or maybe its a coke head or something like that.

    Yeah, that turned white a couple of weeks after I pulled it from V3. Hence my post above asking if V3 could cause tubes to go bad. I now believe that the tube was dying and it so happened to be in V3.

    Lost vacuum. I've had that happen a few times with new production tubes.

    IF you hear crackling tap on the tube if it doesn't cause the crackling its not the tubes. More than likely if its eating tubes the fault is on the pcb somewhere.
