With a variac, monitoring the current draw while You raise the voltage, no, no you won't.
If the problem lies somewhere else than in the power tubes, yes You probably will.
If you haven't already that is.
Blindly replacing the fuse(s) is a recipie for a hefty repair bill.
If You have the equipment and the knowledge how to use it, by all means do it DIY style, but techs are there for a reason, do use them.
