I find that heater filaments pop more often when they are cold and the unit hasn't been turned on for a long time. Fuses do this, too.
Think it has to do with the reduced resistance in the cold causing larger influx of current. Once the tube is warmed-up the filament resistance rises, lowering current flow.
For amps that have been sitting for awhile, I ramp them up with a Variac.
