An autotransformer or variac would serve equally well. As Kalee20 said, a few minutes plugged into a higher voltage won't hurt the set and will allow you to check the heater voltage.
You wouldn't, and you are right. It's just that I'm thinking of my setup in which I use one with which I also make use of it's settings to slightly under run my soldering iron so it comes readily to mind. After I wrote it I did think of an auto transformer as an option too, and obviously a variac would be ideal.
