I once had a run away 6AS7G. It's a tube that gets stronger and stronger as it heats up.
If you have a tube tester, set it to continuous bias. You will notice the parameters keep rising, a lot.
Remember that the 6AS7G naturally rises, but there is a point where it stops. A bad tube will continue. Don't let the tube rise too much, it may damage the tester.
