If it's gonna go, it's gonna go with or without a variac.  If you have 
any grid current when you turn the amp on, immediately shut'r down and 
yank the tube.

If you have some kind of step start for the amp you can try wiring a 
100W lightbulb in series with the power mains.  100W bulb may not be 
stiff enough - may have to have a 200W bulb.  Plenty of other people on 
this list who can comment about that.
